NSTALLATION
Installing the Module into a Switch
CAUTION: This Module is not hot-insertable or
hot-swappable. Always make sure that the Switch is
powered down and disconnected from the mains before
installing or removing a Module. Use the following
instructions when installing or removing a Module.
CAUTION: This Module is only designed to work with
the 3Com SuperStack 3 Switch 4900 series.
To install the Module:
1 Ensure that the Switch is disconnected from the mains
power supply and that you are wearing an anti-static
wristband connected to a suitable earth point.
2 Place the Switch on a flat surface. Using a suitable
screwdriver, remove the blanking plate from the rear of
the Switch. Do not remove any other screws from the
rear of the Switch.
3 Keep the blanking plate and screws in a safe place. If
you remove the Module at any time, you must replace
the blanking plate to prevent dust and debris entering
the Switch and to aid the circulation of cooling air.
4 Hold the Module so that the text on the front panel is
upright, and insert it into the Switch, ensuring the back
panel is flush against the back of the Switch. Tighten
the three captive thumbscrews securing the Module with
a suitable tool.
5 To activate the Module:
a Ensure that the Switch is powered-up.
b Remove the protective plastic covers from the fiber
connections on the Module.
c Plug the MT-RJ connector on the fiber cable into the
fiber port on the Module.
d Connect the other end of the fiber optic cable to a
device fitted with a 1000BASE-SX Gigabit Ethernet
connection.
6 Check the LEDs on the front of the Switch and the rear
of the Module to ensure that the Module is operating
correctly. Refer to "LEDs" below for more information.
Removing the Module from a Switch
