About the Switch

4400

The Switch 4400 is a stackable 10/100 Mbps device and provides

high-performance work groups with a backbone to server connection.

The Switch 4400 allows Cascade, Gigabit Ethernet or Fast Ethernet Fiber

connections when expansion modules are installed in the expansion slots

on the rear of the unit. You can also add the Switch 4400 to any

SuperStack

system as your network grows.

WARNING: RJ-45 Ports. These are shielded RJ-45 data sockets. They cannot

be used as standard traditional telephone sockets, or to connect the unit to a

traditional PBX or public telephone network. Only connect RJ-45 data

connectors, network telephony systems, or network telephones to these

sockets.

Either shielded or unshielded data cables with shielded or unshielded

jacks can be connected to these data sockets.

10BASE-T/

100BASE-TX Ports

The Switch has 24 or 48 auto-negotiating 10BASE-T/100BASE-TX ports

configured as Auto MDIX (cross-over). These ports automatically provide

the appropriate connection. Alternatively, you can manually set these

ports to 10BASE-T half duplex, 10BASE-T full duplex, 100BASE-TX half

duplex or 100BASE-TX full duplex. The maximum segment length is

100 m (328 ft) over Category 5 twisted pair cable.

LEDs Ta b le 5

lists LEDs visible on the front of the Switch, and how to read their

status according to color. For information on using the LEDs for problem

solving, see “

Power Socket The Switch automatically adjusts its power setting to any supply voltage

in the range 90-260 VAC.

Redundant Power

System Socket

To protect against internal power supply failure, you can use this socket

to connect a Switch 4400 to a SuperStack 3 Advanced Redundant Power

System (RPS). See “

Connecting a Redundant Power System” on page 27.

Console Port The console port allows you to connect a terminal and perform remote or

local out-of-band management. The console port uses a standard null

modem cable and is set to auto-baud, 8 data bits, no parity and 1 stop

bit.

Expansion Module

Slots

You can use these slots to install Expansion Modules. These allow the

Switch to support various forms of connection and add extra functionality

to your Switch. Contact your supplier for more information.

WARNING:

When an Expansion Module is not installed, ensure the

blanking plate is fitted by tightening all screws with a suitable tool.
