How To Install An Add-On Module

Follow the following steps to install the add-on modules in the EtherFast 10/100 Auto-Sensing Hub (EFAH16 or EFAH24).

1.Power off the hub and remove the AC power cord from the hub.

2.Remove all RJ-45 cables from the all the ports in the hub and if the hub is on a rack remove the hub from the rack

3.Using a Philips screw driver, remove the screws holding the small cover panel on the back of the hub. The size of the panel is about 8.1cm by 3.5cm (3.1" x 1.4"). You will need the screws to secure the add-on module later.

4.Ground yourself properly and remove the add-on module from its pack- age.

5.Hold the module so the chips and the components on the add-on module are facing up. If the module has a daughter board (a bigger board mounted on the main board of the add-on module), the bottom of the daughter board should be facing up. Insert the module into the back of the hub.

6.The add-on module will slide in until it comes to a stop. Push the mod- ule to make sure it makes a proper connection. Note: Do not use too much force, you can bend the metal panel on the add-on module.

7.Secure the module in place with the two screws.

8.If used on a rack, mount the hub back on the rack. Reconnect the RJ-45 cables and the AC Power cord. Note: do not connect any cables to the port(s) that will be used by the add-on Module (see page 14 to find which ports can't be used when using an add-on module).

9.Connect your Fiber cable or RJ-45 cable to the add-on Module. Turn on the hub.
