8271 NWAYS ETHERNET LAN SWITCH
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.

Default Passwords
LED Color Indicates
Port Status LEDs
Packet Yellow Packets are being transmitted/received on the
port.
Off No packets are being transmitted/received on
the port.
Status Green A link is present, and the port is enabled.
Green
flashing
A link is present, but the port is disabled.
Off No link is present.
Expansion Module Port Status LEDs
Packet Yellow Packets are being transmitted/received on the
Expansion Module port(s).
Off No packets are being transmitted/received on
the Expansion Module port(s).
Status Yellow A valid Expansion Module is installed in the
Switch.
Yellow
flashing
An unrecognized Expansion Module is installed
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.
1 – 8 Off The Switch is stand-alone.
LED Color Indicates
Power/Self Test LED
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.
