Frequently Asked Questions - NEsT 8P P 6202 Pentagram

What is a switching hub and how does it differ from an ordinary hub?

A switching hub (or switch) connects multiple computers in a network. Unlike an ordinary hub that sends data to all connected devices, a switch sends data only to the target computer, which increases performance and reduces network load.

How do I install the Pentagram NEsT 8P switch?

Connect the power adapter to the switch and plug it into an electrical socket. Then, use network cables (RJ-45) to connect your computers or other network devices to any of the 8 ports. The switch automatically configures itself.

Can I connect the switch to another switch?

Yes, any port can be used to uplink to another switch. The auto MDI/MDI-X feature eliminates the need for a crossover cable.

What do the LED indicators mean?

The POWER LED (red) indicates the switch is on. The SPEED LED (green) is off for no link or 10 Mbps link, and on for 100 Mbps link. The LINK/ACT LED (green) is solid when a link is established and blinks during data transfer.

What is auto-negotiation and how does it work?

Auto-negotiation allows each port to automatically select the best available speed (10 or 100 Mbps) and duplex mode (half or full) when connecting to another device. For example, if the connected device supports 100 Mbps with auto-negotiation, the switch will operate at 200 Mbps (100Base-TX full duplex).

Does the switch support full duplex mode?

Yes, it supports both half duplex and full duplex on all ports. Full duplex allows simultaneous sending and receiving, doubling the effective bandwidth.

What type of cables should I use?

For 10 Mbps connections, use UTP category 3, 4, or 5 cables. For 100 Mbps connections, use UTP category 5 cables. All cables must have RJ-45 connectors.

What is flow control and why is it important?

Flow control prevents data loss when transmitting and receiving at different speeds. The switch supports back-pressure for half duplex and IEEE 802.3x for full duplex modes.

Do I need to configure the switch before use?

No, the switch is plug and play. It automatically detects the speed and duplex mode for each connected device. No software installation or configuration is required.

What are the physical dimensions of the switch?

The dimensions are 160 mm wide, 94 mm deep, and 30 mm high (160 x 94 x 30 mm).

Quick installation manual

Thank you for purchasing our switching hub PENTAGRAM NEsT 8P. We believe it will meet your expectations and will serve you well.

In this manual we will describe the most important issues related to the device and its installation.

A switching hub, or switch, for short, is a device which makes it possible to connect several computers into a network. Using our device, you will be able to share data with other users very quickly. The network connection will help you to work more efficiently, and to play the newest computer games supporting multi-player mode with your friends. A switch differs from an ordinary hub in a way that its performance is higher, and it reduces network load. The increased performance and reduced network load is gained by port switching, i.e. sending data only to target computers (an ordinary hub sends data to all the computers in a network, thus significantly slowing down transfers).

Installation and operation of the switching hub PENTAGRAM NEsT 8P is easy. As the device supports major standards, it allows to create a new network or extend an existing one with ease.

Requirements

• Computers with NICs working in one of the supported standards (10Base-T, 100Base-TX)
• Network cables UTP cat. 3, 4 or 5 (10 Mbps), UTP cat. 5 (100 Mbps), with RJ-45 connectors.

Device functions

• Every port supports the autocrossover function (MDI/MDI-X), enabling fast connection of the switch with other devices or computers.
• Store and Forward function additionally increases bandwidth by filtering wrong packets.
• Speed autonegotiation for each port individually.
• Support for flow control modes – back-pressure (half duplex) and IEEE802.3x (full duplex), in order to prevent errors when transmitting and receiving data with different speeds.
• Signal diodes allow for quick determination of network operation status.
• No user configuration needed. Just plug it in and work. The switch will automatically set transmission speed and mode for individual ports depending on the connected devices (e.g. PC/printer).
• Support for full duplex mode helps to double the effective network bandwidth.

Device external look

Front panel

On the device front panel, there are diodes displaying the status of the device and individual ports. One diode POWER shows the device power status, 8 diode pairs show the status of individual ports' operation.

Name Color Function
POWER Red On: the power is on
10/100 Green		Off: no link or link 10 Mbps
		On: link 100 Mbps
LINK/ACT	Green	On: link with other device
		Blinking: data transfer

Back panel

On the back panel, there are RJ-45 ports for connecting computers and other network devices through network cables and power connector.

Device operation

1. Connect the power adapter (supplied) to the power connector on the back panel of the device, then connect the power adapter to an electrical socket.
2. Connect the computers and other network devices to the RJ-45 connectors on the back panel through network cables (not supplied). You may connect any port of the device to another switch (Uplink).

Half duplex and full duplex

PENTAGRAM NEsT 8P supports half and full duplex modes in 10Base-T and 100Base-TX modes.

Half duplex – data cannot be sent and received simultaneously. They are sent after the reception has finished.

Full duplex - data can be sent and received simultaneously. This mode doubles the channel bandwidth.

Full duplex transmission is possible:

• Between devices connected directly (e.g. switch-switch, switch-PC)
• When both devices support full duplex mode
• When both devices work in the same autonegotiation mode (e.g. autonegotiation–autonegotiation, or no autonegotiation–no autonegotiation.)

Autonegotiation

Each device port has a link speed autonegotiation function. It allows to choose the best available speed for each separate port during connection with other device.

The table represents the modes in which the switch will work after connection with various devices.
