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.
