SUPERSTACK® 3 SWITCH 3300

QUICK REFERENCE GUIDE

Hardware Features

The illustration shows a Switch 3300 24-port

(3C16980A). The port and LED layout is different for

a Switch 3300 12-port (3C16981A).

10BASE-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.

Status LEDs

These LEDs provide a quick method of

diagnosing problems. See LEDs for more informa-

tion.

Power 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.

Redundant Power System Socket

Use this socket

to connect a SuperStack 3 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

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

to install an optional Expansion Module. 3Com pro-

vides a range of Expansion Modules; contact your

supplier for availability.

Matrix Port

Use this port to connect a Matrix

Cable, which allows you to stack Switch units

together.
