電源コードとACアダプター

There are several LEDs on the control panel and on the drive carriers to keep you informed of the status of the system. Most SC811 models include two buttons on the chassis control panel: a reset button and an on/off switch. This chapter explains the meanings of the LED indicators and the appropriate responses.

3-2 Control Panel Buttons

There are two push-buttons located on the front of the chassis. These are (from left to right) a reset button and a power on/off button.

- Reset: The reset button is used to reboot the system.

- Power: The main power switch is used to apply or remove power from the power supply to the server system. Turning off system power with this button removes the main power but keeps standby power supplied to the system. Therefore, you must unplug system before servicing.

3-3 Control Panel LEDs

The control panel located on the front of the SC811 chassis has five LEDs. They provide you with critical information related to different parts of the system. This section explains what each LED indicates when illuminated and any corrective action.

• Information LED: Alerts operator of several states, as noted in the table below.

Informational LED
Status Description
Continuously on and red	An overheat condition has occurred. (This may be caused by cable congestion.)
Blinking red (1Hz) Fan failure	check for an inoperative fan.
Blinking red (0.25Hz) Power	failure, check for a non-operational power supply.
Solid blue	Local UID has been activated. Use this function to locate the server in a rack mount environment.
Blinking blue	Remote UID is on. Use this function to identify the server from a remote location.

- NIC2: Indicates network activity on GLAN2 when flashing.

• NIC1: Indicates network activity on GLAN1 when flashing.

Chapter 5

Rack Installation

This chapter provides simple instructions for installing this chassis into a rack. This chassis does not support Telco rack installation.

5-1 Preparing for Setup

Please read this section in its entirety before beginning the installation procedure.

Choosing a Setup Location

Decide on a suitable location for the rack. It should be a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated. Place it near a grounded power outlet.

• Leave at least 25 inches clearance in front of the rack to open the front door completely.
• Leave approximately 30 inches of clearance in the back of the rack to allow for sufficient airflow and ease in servicing.
• Install in a restricted access location, such as a dedicated equipment room or service closet.

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be greater than the ambient temperature of the room. Install the equipment in an environment compatible with the manufacturer's maximum rated ambient temperature (TMRA).

Adequate Airflow

Equipment should be mounted into a rack so that the amount of airflow required for safe operation is not compromised.

Circuit Overloading

Avoid overloading the power supply circuitry or any overcurrent protection equipment. Use equipment nameplate ratings to calculate your requirements.

Reliable Ground

A reliable ground must be maintained at all times. To ensure this, ground the rack, itself. Pay attention to power supply connections other than the direct connections to the branch circuit, such as power strips.

Physical Rack Precautions

Warning: Follow these guidelines to prevent injury. Take all precautions to ensure the system remains stable. The following guidelines are provided to ensure your safety.

• Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with the full weight of the rack resting on them.
• In single rack installation, stabilizers should be attached to the rack.
  • In multiple rack installations, the racks should be coupled together.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. If this is the only unit in the rack, mount it at the bottom.
• Always make sure the rack is stable before extending a component from the rack. Extend only one component at a time. Extending two or more simultaneously may cause the rack to become unstable.
  • This chassis does not support Telco rack installation.

General Server Precautions

• Review the electrical and general safety precautions that came with the components you are adding to your chassis.
  • Determine the placement of each component in the rack.

• Install the heaviest server components on the bottom of the rack first, and then work up.

• Use a regulating, uninterruptible power supply (UPS) to protect the server from power surges, voltage spikes and to keep your system operating in case of a power failure.
• Allow the hard drives and power supply modules to cool before touching them.
• Always keep the rack front door, all panels and all components on the servers closed when not servicing, to maintain proper cooling.

5-2 Rack Mounting Instructions

This section provides information on installing the SC811 chassis into a rack unit with the rails provided. There are a variety of rack units on the market, which may mean the assembly procedure will differ slightly. Refer also to the installation instructions that came with the rack unit.

Note: The rails will fit a rack between 29" and 35.25" deep.

Identifying the Sections of the Rails

The chassis package includes two rail assemblies in the rack mounting kit. Each assembly consists of two sections: an inner fixed chassis rail that secures directly to the server chassis and an outer rack rail that secures directly to the rack itself.

Rail Brackets

The chassis package includes four rail brackets and two chassis mounts. The rail brackets have long ovals used to adjust the length of the rails when mounting. The chassis mounts (both short) have one square hole.

Figure 5-1: Inner and Outer Rails

Separating the Inner and Outer Rails

1. Pull the inner rail (A) from the outer rail (B) as far as possible.
2. Depress the locking tab (C) to pull the inner rail completely out.
3. Repeat steps 1 and 2 for the other rail.

Figure 5-2: Rail Installation

Installing the Inner Rail

1. Align the chassis rail with the side of the chassis.
2. Secure the rail to the chassis using six M5 flat head screws.
3. Repeat steps 1 and 2 for the other side of the chassis.

Figure 5-3. Rack Brackets

Installing the Outer Rails to the Rack

1. Confirm that the inner rails have been separated from the outer rails.
2. Locate the rail brackets in the accessories box. The chassis package includes four rail brackets and two chassis mounts. The rail brackets have long ovals used to adjust the position of the rails when mounting. The chassis mounts (both short) have one square hole.
3. Secure the short brackets to the front of the outer rails with two M4 screws.
4. Secure the long brackets to the outer rails using two M4 screws. Tighten the screws loosely so the bracket can slide back and forth.
5. Position the outer rail and brackets in the rack at the desired level.
6. Secure the front of the rail to the rack using two M5 rack screws.
7. Slide the rear bracket so that it snugly fits into the rack. Secure the rear bracket to the rack using two M5 screws.
8. Tighten the screws that secure the rear bracket to the rail.
9. Repeat these steps with the other chassis rail.

Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over.

Figure 5-4: Mounting the Chassis
(Note: This figure is for illustrative purposes only. Always install servers into racks from the bottom up.

Installing the Chassis into a Rack

Chassis Installation

1. Confirm that the chassis includes the inner rails (A) and that the outer rails (B) are installed on the rack (See Figure 5-3)
2. Align the chassis rails (A) with the front of the rack rails (C).
3. Slide the chassis rails into the rack rails, keeping the pressure even on both sides (you may have to depress the locking tabs when inserting). When the server has been pushed completely into the rack, you should hear the locking tabs "click".
4. (Optional) Insert and tightening the thumbscrews that hold the front of the server to the rack.

Caution: Do not pick up the server by the front handles. They are designed to pull the system from a rack only.
