IBM F12 Quick Reference Manual

Hardware Features
The Illustration shows a Switch Model F24
(02L0879). The port and LED layout is different for a
Switch Model F12 (02L0878).
10BASE-T/100BASE-TX Ports These auto-negotiat-
1
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.
Status LEDs These LEDs provide a quick method of
2
diagnosing problems. See "LEDs" for more informa-
tion.
Power Socket Insert the power cord into this
3
socket to connect the Switch to the main power
supply. Note that there is no On/Off button.

Redundant Power System Socket Use this socket
4
to connect an Advanced Redundant Power System
(RPS) to the Switch, and therefore protect against
internal power supply failure.
Console Port Use this port to connect a terminal or
5
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.
Expansion Module Slot Remove the blanking plate
6
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.
Matrix Port Use this port to connect a Matrix
7
Cable, which allows you to stack Switch units
together.
