Illustration shows Model E24 (24-port model). Port and
LED layout is different for Model E12 (12-port model).
1 10BASE-T Ports These ports provide a 10Mbps bandwidth
to Ethernet devices. The ports are configured as MDIX
(cross-over) and support a maximum segment length of
100m (328ft) over Category 3, 4 or 5 twisted pair cable.
Status LEDs Status LEDs provide a quick method of diag-
2
nosing problems. See "LEDs" for more information.
10BASE-T/100BASE-TX Ports These auto-negotiating ports
3
can automatically detect the speed of a link and provide a
10Mbps connection to Ethernet devices or a 100Mbps con-
nection to Fast Ethernet devices. These ports are config-
ured as MDIX (cross-over) and support a maximum segment
length of 100m (328ft) over Category 5 twisted pair cable.
Unit LEDs Unit LEDs indicate the position of this unit in the
4
stack.
Power Socket Insert the power cord into this socket to
5
connect the Switch to the main power supply. Note that
there is no On/Off button.

6 Redundant Power System (RPS) Socket Use this socket
to connect an RPS to the Switch, and protect against inter-
nal power supply failure.
7 Console Port Use this port to connect a terminal or termi-
nal 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.
8 Expansion Module Slot Remove the blanking plate to
install an optional Expansion Module that provides an addi-
tional high-speed link, or a Matrix Module that provides
four matrix ports for stacking up to four units.
9 Matrix Port Use this port to stack two units with a single
Matrix Cable, or use in conjunction with a Matrix Module
and multiple Matrix Cables to stack up to four units.
10 Transceiver Module Slot Remove the blanking plate to
install a transceiver module and provide a 10Mbps connec-
tion. Transceiver modules are available for a wide range of
media support. Contact your local supplier.
