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

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.
