Cabletron Systems ELH100 manual Installing an Optional Module into the Hub

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.

DO NOT install slide-in modules with the hub powered on. Be sure you power off the hub before installing any module.

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.
