You can connect the hub to another 100Base-FX Switching hub
or to a PC through the fiber-optic module.
Make the connection as follows or refer to the installation guide
of the module to get more.
1. Make sure the port#15, port#16 of DH-1600 or port#12,
port#24 of DH-2400 on the hub is free.
2. Unplug the power. Remove the two screws of the expansion
