Installing an Optional Module into the Hub

Optional modules are available for media extension and internal switching

between repeater buses and management. These modules can be

installed into the modular slots on the left side of the hub. The Agent

Module must be installed in the lower slot, and all other modules in the

upper slot.

To install an optional module into the hub, do the following:

1. Disconnect power to the hub.

2. Remove the blank metal plate (or a previously installed module) from

the appropriate slot by removing the two screws with a flat-head

screwdriver. A switch/media module can be installed in the upper slot

on the front of the hub. An Agent Module can be installed in the lower

slot on the front of the hub.

3. Before opening the package that contains the module, touch the bag

to the hub casing to discharge any potential static electricity.

4. Remove the module from the anti-static shielded bag.

5. Holding the module level, guide it into the carrier rails on each side

and gently push it all the way into the slot, ensuring that it firmly

engages with the connector.

6. If you are sure the module is properly mated with the connector,

tighten the retainer screws by hand to secure the module in the slot.

7. Connect power to the hub.

DO NOT install slide-in modules with the hub powered

on. Be sure you power off the hub before installingany

module.
