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.

in the Switch.

Off No Expansion Module is installed in the Switch.

Unit LEDs

1 – 8 Green Indicates the position of the Switch in the

stack and that a link is present. Note that

although there are eight LEDs, only four

Switch units can be stacked at present.

Green The Switch is powered-up.

Green

flashing

The Switch is either downloading software or

is initializing (which includes running a Power

On Self Test).

Yellow The Switch has failed its Power On Self Test.

Off The Switch is not receiving power.
