4 Replace the blanking plate over the empty transceiver module slot in
the rear of the hub, and use the two screws to fix the blanking plate
in place.
For information on how the hub’s configuration is affected by the
removal of the management module, refer to
“Removing
Management From the Hub”
on
page 25
.
Powering On the Hub or Stack
When you have fitted the management module correctly, you can
power on the hub. If the hub is connected to other Dual Speed
Hub 500 units with cascade cables, those units become managed
units within 20 seconds.
For information on making a management connection to the hub or
stack, refer to
“Methods of Management”
on
page 28
.
In rare circumstances, repeatedly powering units off and on in a stack
may cause an interruption to the management of the stack. To avoid
this, it is recommended that the bottom unit in the stack is powered
on first, followed by the unit above it, and so on.
Upgrading the Smart Agent Version
Supplied with every management module you will find the latest
management agent software. You should check the version on your
Dual Speed Hub 500 by either:
■
Entering
system display
on the Command Line Interface
(CLI);
or
■
Accessing the Unit Status page through the Web Interface.
If the version number is less than the version supplied with your
management module, upgrade the agent following the instructions
in
“Upgrading the Management Software”
on
page 69
(CLI) or
“Software Upgrade”
on
page 99
(Web interface).
