Fitting a Transceiver Module
The MSH Switch 1005 has a slot for one Transceiver Module. You should
fit the Transceiver Module before you fit the Expansion Module and
before you install the Switch 1005 into the MSH chassis. Fitting the
Transceiver Module is described in the User Guide that accompanies it.
If you have an Expansion Module fitted to your Switch 1005 and you
install four 4 Port 10BASE-T Transceiver Modules with all backplane
connections enabled, Ethernet backplane E3 (port 27) will automatically
disable and you will lose the ability to configure it. Removing one of the
Transceiver Modules will reinstate port 27.
Fitting an Expansion Module
Fitting an Expansion Module allows you to increase the number of
ports for your Switch 1005; you should fit it to the Switch 1005 before
installing the pair into the MSH chassis. The Expansion Module provides
three locations for Transceiver Modules. You should fit these before you
fit the Expansion Module. Fitting the Expansion Module is described in
the User Guide that accompanies it.
