MODELS F12 AND F24
QUICK REFERENCE GUIDE
Hardware Features
The Illustration shows a Switch Model F24
(02L0879). The port and LED layout is different for a
Switch Model F12 (02L0878).
110BASE-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.
2Status LEDs These LEDs provide a quick method of
diagnosing problems. See “LEDs” for more informa-
tion.
3Power 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.
4Redundant 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.
5Console 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.
6Expansion 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.
7Matrix Port Use this port to connect a Matrix
Cable, which allows you to stack Switch units
together.
