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 Table 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 “Solving Problems Indicated by LEDs” on page 46.

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 24.

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.

Choosing a Suitable

Site

The Switch is suited for use on a desktop, either free standing or

mounted in a standard 19-inch equipment rack. Alternatively, the Switch

can be mounted in a wiring closet or equipment room, as an aggregator

for other Hubs and Switches. A rack-mounting kit containing two

mounting brackets is supplied with the Switch.

CAUTION: Ensure that the ventilation holes are not obstructed.

When deciding where to position the Switch, ensure that:

■

Cabling is located away from:

■

sources of electrical noise such as radios, transmitters and

broadband amplifiers.

■

power lines and fluorescent lighting fixtures

■

The Switch is accessible and cables can be connected easily.

■

Water or moisture cannot enter the case of the Switch.

■

Air-flow is not restricted around the Switch or through the vents in the

side of the Switch. 3Com recommends that you provide a minimum of

25mm (1in.) clearance.

■

Air flow around the Switch does not exceed 40

°C

(104

°

F).
