1. Introduction

The SurgeX® Squid is a universal 120/240V, 12A@120V/10A@240V, AC and DC power distribution unit with power conditioning, control and monitoring. Designed for flexibility, Squid's compact form factor may be wall or table mounted, or mounted against the face of an equipment rack. The internal web server provides configuration, output control, monitoring, and retrieval of data logs. Multiple security and communication interface options are supported.

Squid incorporates SurgeX Multi-Stage surge suppression and EMI/RFI filtering technology. This protection safeguards the DC output power as well as the AC outlets.

The extensive programming capabilities of the Squid provide advanced sequencing and scheduling operations. Triggers can be programmed to activate on an "if X then do Y then do Z when no longer X" basis. Trigger sources include: various AC power measurements, scheduling, and A ut o ping . Actions include: turning receptacles on and off, cycling a receptacle, executing previously-defined sequences, and putting a unit into shutdown. For example, an action can be created to power cycle a network appliance if it fails to respond to a ping.

Metering is performed at the system level, and includes:

• AC Line Voltage
  • AC Neutral-Ground Voltage
• AC Current

• AC Power

• AC Line Frequency

• AC Power Factor
  • AC Voltage Crest Factor
• AC Energy

Measurements (voltage, current and power) are true RMS. Thus, the current draw and energy consumption of non-linear electronic loads which have a power factor of less than unity will be correctly reported.

Physical interfaces:

• [1] IEC320 C14 AC inlet
• [4] IEC320 C13 AC outlets
• [5] DC terminal blocks:

○ [2] DC output 1 (either 12V or 24V, depending on model)
○ [2] DC output 2 (either 12V or 24V, depending on model)
○ [1] 5V DC output

• [2] USB-A 5V DC output (power only)

• [1] Network RJ-45
• [1] USB-micro AB
• [2] Recessed pushbuttons

The four AC outlets and two 12/24V DC output banks are individually controllable. It is also possible to toggle the AC input to the AC/DC converter feeding the DC Output 1 and DC Output 2 banks through the REST API.

Squid models:

Model	DC Output 1	DC Output 2	Configuration (May be changed)
SX-DC-8-12-120	12V	12V	120V
SX-DC-8-12-230	12V	12V	230V
SX-DC-8-24-120	24V	24V	120V
SX-DC-8-24-230	24V	24V	230V
SX-DC-8-1224-120	24V	12V	120V
SX-DC-8-1224-230	24V	12V	230V

2. Installation

Squid is designed to be installed horizontally or vertically, mounted to a wall or table. It may also be mounted to the face of an equipment rack. Use the integral mounting brackets to install Squid following the appropriate local regulations and requirements. Four of the following minimum screw sizes must be used:

Minimum of #10 screw with no less than a 0.250" head diameter if using the (4) round holes. Minimum of 14 -20" thread with no less than a 0.430" head diameter if using the slotted holes.

2.1 AC Power

Squid has a total of 4 AC receptacles. Each receptacle is rated for a maximum load of 12A (North America)/10A (EU, Australia, South America), and the total load must not exceed 12A(10A). Plug the equipment cords into the receptacles as needed. The receptacles are numbered 1 through 4. This same numbering is used in the control interface.

Connect power to the unit using an appropriately rated 3 wire grounding type power cord into a suitable wall or floor receptacle (120V, 12A North America; 240V, 10A EU, Australia, South America). Do not plug the unit into a relocatable power tap. Check the outlet for correct polarity and presence of a ground conductor before plugging the unit in.

2.2 DC Power

Connect DC equipment power cords to the five screw terminals using a small screwdriver. 5V power is also available at the two USB-A receptacles for device charging. Each DC output bank incorporates overload protection. Do not interconnect DC outputs.

Do not use a DC equipment power cord longer than 3m.

Do not load the DC outputs beyond these ratings:

Model	DC Output 1 Rating	DC Output 2 Rating	Combined DC1 + DC2 Rating	5V USB Type A Rating	Combined 5V Output Rating
SX-DC-8-12-X	5A @ 12V	5A @ 12V	10A @ 12V	1A @ 5V	3A @ 5V
SX-DC-8-24-X	2.5A @ 24V	2.5A @ 24V	5A @ 24V	1A @ 5V	3A @ 5V
SX-DC-8-1224-X	2.5A @ 24V	5A @ 12V	N/A	1A @ 5V	3A @ 5V

2.3 Ethernet

The RJ45 connector for Ethernet is situated on the rear panel beside the Serial connector. The default IP Address is DHCP assigned. To find IP address of the device, please use the discovery tool at ametekesp.com. The mDNS protocol is supported for dynamic device discovery.

The default username is admin, and the default password is Adm1nXXXXXX where XXXXXX are the last six characters of the MAC address.

2.4 USB OTG

The USB-micro AB connector is for OOB diagnostics and troubleshooting IP connectivity issues. To use, please use the discovery tool at ametekesp.com or manually enter the static IP address 169.254.10.100 into a supported browser. The web server will always be accessible at 169.254.10.100 through this USB port. The web server on this interface cannot be changed, and will always be unsecured HTTP at port 80.

3. LED Indicators

Squid has a total of nine LED Indicators:

• [4] AC Outlet. When illuminated, the corresponding AC outlet is on
• [2] DC Output. When illuminated, the corresponding DC output is on
• [2] Ethernet Connection and Activity
• [1] Surge Protection OK (on opposite side of pictured view)

4. Buttons

There are two recessed pushbuttons located to the right of the Ethernet RJ-45 jack. The Hardware Reset button is furthest from the RJ-45 jack, and the Software Reset button is closest.

4.1 Hardware Reset

The Hardware Reset button performs a hard reboot of the processor. This hard reboot will immediately switch controlled outlets off, removing power to connected equipment on all outputs except the 5V output.

4.2 Software Reset

The Software Reset button is a multi-functional control depending on length of press. If the button is held for greater than 10 seconds, the unit resets itself to factory defaults, and all custom configurations are erased. If the button is held for less than 10 seconds, the unit will perform a software reset that will not reset any data, or power cycle the connected equipment.

5. Web Server

Squid's internal web server provides a comprehensive portal for configuration, monitoring, and control.

5.1 Login

The Login page is the first page displayed when a web browser makes a connection to the Squid. Enter a valid user name and password in the "User Name" and "Password" fields, and press "Login" to log in.

5.2 Power Management

The Power Management page provides information and status for the whole unit and individual outlets, as well as basic control of outlets. The top right section of the page provides system status.

5.3 Reports

The Reports page displays data collected by Squid, and stored to its internal memory. The data is presented in two groups: Time Stamped Events and Historical Data.

Time Stamped Events are recorded, with a date and time of occurrence, when a condition meets established criteria. Squid uses a Real Time Clock (RTC) synced to an Internet time server, and backed up by an internal battery. For the most accurate time stamps and to eliminate clock drift, we suggest verifying the NTP connection.

The types of events which may be recorded are:

• Triggers
• Surge Protection Failed
• Power Outage
• Network Events
• Outlet Changes
• Shutdown Events
• Firmware Upgrades

Historical Data is a record of measured electrical parameters, and may be adjusted to sample certain items at specific intervals. The available parameters are:

Use SSL	A switch that will enable or disable SSL when attempting to connect to the LDAP server. This is a separate option than the port number, in the case that a site is using a nonstandard port for authentication, but still wants the ability to specify encryption. We always suggest using encryption when using LDAP.
Base DN	The base point in the directory tree where the user distinguished name search will begin.
User DN	The distinguished name of a user that will be used to authenticate. Multiple users are supported by using macros. For example in the above image, the username testUser attempts to log in, and the User DN pulls the name “Test User” from the user’s definition for use in the authentication to replace the string %FullName%.
TLS Require Cert	This specifies how to handle server certificates during TLS negotiations. Never: the client never asks the server for a certificate. Allow: the client will ask for a certificate; if none is provided the session proceeds normally. If a certificate is provided but the client is unable to verify it, the certificate is ignored and the session proceeds normally, as if no certificate had been provided. Try: the certificate is requested, and if none is provided, the session proceeds normally. If a certificate is provided and it cannot be verified, the session is immediately terminated. Demand: the certificate is requested and a valid certificate must be provided, otherwise the session is immediately terminated.
Certificate File	This is the certificate that will be sent to the LDAP Server when/if requested.
User Name	The information for a user that is defined in the Users page. The first part (name), is accessible by the %FullName% macro, and the second part (username) is accessible with the %UserName% macro.
Password	The password for the given user to test the LDAP server configuration.
Test User	A button to send an authentication request using the given settings for the user and password above. NOTE: Settings should be saved using the “Save Settings” button at the bottom of the page before testing a configuration change.

5.4.4 Triggers Setup

The Triggers Setup page allows for the modification of Triggers. Triggers define event logging parameters, and allow configuration to automatically control and protect connected equipment.

Triggers are categorized into three types, AutoPing, Threshold with Samples, and Schedule, but all have the same possible actions. Actions can either be on the onset (Trigger/Alarm Actions) or offset (Clear Actions) of a trigger. All Triggers are logged, along with the associated actions.

Trigger Types
Item	Description
Threshold with Samples	Uses measurements over an allotted time to take an action. This trigger type is configurable to act very quickly or very slowly depending on environmental/system needs.
AutoPing	Issues a ping function on a periodic basis to determine if an IP asset is accessible.
Schedule	Uses the device time to issue a one time or periodic command. We suggest ensuring the NTP server is updating correctly to use the schedule trigger.

Action Types
Item	Description
None	Do not take any action, only log the event. This is useful as a Clear Action when an action should persist, or for both Alarm and Clear actions when just logging the event is desired.
Power On	Power on a specific outlet if the outlet configuration allows it.
Power Off	Power off a specific outlet if the outlet configuration allows it.
Reboot	Reboot a specific outlet if the outlet configuration allows it. If an outlet is already off when this command is issued, the outlet will simply turn on after the outlet specific reboot delay time.
Run Sequence	Run a specific sequence.
Enter Shutdown State	Put the device into a shutdown state. This state turns off all outlets (unless they are configured for always on). The only way to clear a shutdown state, is another trigger, a button on the web interface, or a REST API command.
Clear Shutdown State	Clear the device's shutdown state. Clearing the device's shutdown state will cause the outlets to follow the logic defined by the On Shutdown Clear setting.

5.4.4.1 Threshold with Samples

The Threshold with Samples trigger uses a number of measurements to decide when to take action. The trigger is able to be configured to act quickly, or slowly, depending on the number of measurement samples used. A new sample is available every 50ms, with the minimum samples being used for a trigger being 1 sample, and the maximum being 20 samples.

Threshold with Samples triggers are evaluated every time a new sample is available. Based on the below "New Trigger" example below, the trigger will alarm or turn on after 5 of any consecutive 10 samples are above 140V.

IP	IP address to be pinged at the period set on the device configuration page.
Fail Count	Number of consecutive failed ping responses needed to trigger the AutoPing trigger.
Success Count	Number of consecutive successful ping responses needed to clear the AutoPing trigger.

5.4.4.3 Schedule

The Schedule trigger uses the internal time of the Squid to easily configure single and recurring events based on time. Only Alarm Actions are used for this trigger.

Item	Options	Description
Repeat	Never	The trigger will only fire when the time reaches the time shown in the configuration the next time.
	One Time	The trigger will only fire once, on the specific date and time shown in the configuration.
	Daily	The trigger will fire every day at the given time.
	Weekly	The trigger will fire every week on the selected day(s) at the given time.

Time	12:00 AM – 11:59 PM	A given time to be used in all scheduling triggers.

5.4.5 Users Setup

The Users Setup page allows for the creation, deletion, and editing of user accounts. Each user will have a unique name, user name, authentication mode, and may be assigned access to specific features.

LDAP and Internal authentication modes are supported.

The following privileges may be assigned or revoked as necessary:

• Trigger Config
• Device Control
• Network Settings
• Software Update
• User Administration

5.4.6 Sequences Setup

The Sequences Setup page allows for the creation and modification of sequences. A sequence is a set of actions to be taken in a specific order, and with a specified delay time between each step. Using sequences avoids manually performing each action, or turning each outlet on or off, individually.

A sequence, as defined for this product, is purely a one-way sequence. That is, you do not use the same sequence to turn outlets on as you use to turn the same outlets off in reverse order. One sequence must be created for the turn-on function, and then a second sequence must be created for the turn-off function.

To create a new sequence, press the "Add Sequence" button. The new sequence must be given a unique name. This name should clearly indicate what the sequence will do, such as "All On", "All Off" or "Stage Equipment On".

To run a sequence to test it, press "Run Sequence". To edit an existing sequence, press the pencil icon. To delete a sequence, press the minus "-" icon.

After a sequence has been saved, it will be available at the Sequences page, and when creating or editing a trigger when run sequence is selected as an action.

*Time delay is specified from the previous sequence item, not from the initial starting point. For example, creating a sequence with "Step 1, 1 second, Outlet 1, On" and "Step 2, 1 second, Outlet

2, On" will turn on Outlet 1 after 1 second, and Outlet 2 on 1 second after

Outlet 1 has turned on. This sequence will not turn on both Outlets 1 and 2 at the same time.

Sequence Actions:

• None (useful for additional time delays)

- State Change

○ On, Off, or Reboot.

5.5 Utilities

Squid contains several utilities to ease the configuration and deployment that may be performed on a per unit basis through several web pages.

5.5.1 File Upload

Squid allows for a variety of files to be uploaded. This is also the method for upgrading the firmware. Current firmware versions can be obtained from the SurgeX website. Squid will not automatically contact SurgeX servers for new firmware. Other files that can be uploaded include a variety of certificates and configurations. By default, Squid ships with a self-signed HTTPS certificate if HTTPS is enabled. A different certificate can be uploaded for use by the HTTPS server by selecting "HTTPS SSL Certificate" under the File Type drop down.

The current configuration may be saved to a file and downloaded for archival. Previously stored configurations may be applied to other units to easily mass configure a larger deployment. IP Settings will not be saved in the Backup Configuration.

5.5.3 Factory Reset

Factory default settings may be applied through the web interface.

- Option to keep or reset network IP settings.

- Web Server settings will be reset. A custom port number will be reset to 80, and SSL will be disabled by default.

5.5.4 Soft Reboot

Adds the ability to reboot the Squid processor. A soft reboot will not change the outlet state or disconnect power from connected equipment. This request will add a message in the event log "Rebooting Adapter Due to User Request".

6. Security

Squid has been designed with security as a priority. All ports and features may be changed or disabled.

6.1 Authentication

Squid supports basic and secure authentication for users and network connections.

6.1.1 802.1X

802.1X network authentication may be enabled for networks requiring supplicant authentication.

6.1.2 SSO (Single Sign-On)

Squid users may be configured to use either Internal or SSO (Single Sign-On) authentication. Internal authentication uses basic usernames and passwords assigned by the administrator on a per-unit basis. SSO authentication uses LDAP (Lightweight Directory Access Protocol) to authorize users, and determine their level of privileges, using Microsoft® Active Directory. While it is possible to use LDAP to authorize users without SSL encryption, we suggest only configuring the connection to the authentication server using SSL encryption to plain text network traffic.

6.2 Interfaces

6.2.1 Network Interface

• Web Server: It is possible to enable and disable the internal web server, change the security from none (HTTP) to TLS 1.2 (HTTPS), as well as change its port. These settings also apply to the REST API.
  • SNMP: Squid supports SNMP V3 for secure communications, with the ability to enable and disable.
