Hardware Features
The Illustration shows a Switch Model F24
(02L0879). The port and LED layout is different for a
Switch Model F12 (02L0878).
1
10BASE-T/100BASE-TX Ports These auto-negotiat-
ing ports can automatically detect the speed of a
link and provide a 10Mbps connection to Ethernet
devices or a 100Mbps connection to Fast Ethernet
devices. The ports are configured as MDIX
(cross-over) and support a maximum segment length
of 100m (328ft) over Category 5 twisted pair cable.
2
Status LEDs These LEDs provide a quick method of
diagnosing problems. See “LEDs” for more informa-
tion.
3
Power Socket Insert the power cord into this
socket to connect the Switch to the main power
supply. Note that there is no On/Off button.
4
Redundant Power System Socket Use this socket
to connect an Advanced Redundant Power System
(RPS) to the Switch, and therefore protect against
internal power supply failure.
5
Console Port Use this port to connect a terminal or
terminal emulator to the Switch, and therefore allow
out-of-band management.
The console port uses
standard null modem cable and is set to
auto-baud, 8 data bits, no parity and 1 stop bit.
6
Expansion Module Slot Remove the blanking plate
to install an optional Expansion Module that pro-
vides an additional high-speed link, or a Matrix
Module that provides four matrix ports for stacking
Switch units together.
7
Matrix Port Use this port to connect a Matrix
Cable, which allows you to stack Switch units
together.
