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 installing any
module.
