Connecting to Network Devices 2-5

Installing a Fast You can install up to four, 2-port Fast Ethernet physical modules on to the Ethernet Physical 7600 Card. Each module can be configured for either 100BASE-Fx or

Module 100BASE-Tx connections.

The 7600 Card is supplied with 12 male/female spacers with which to attach the physical modules.

To install a physical module on to the 7600 Card module, perform the following steps:

1Remove the 7600 Card module from the CELLplex 7000 chassis if it is already installed.

2Remove the plate covering the cutout for the connector from the front panel.

3Hold the physical module at an angle behind the front panel so the connectors on the physical module are aligned with the unoccupied cutout on the front panel, and insert the connector into the cutout. (See 1 in Figure 2-1).

4Lower the card on to the spacers located on the 7600 Card, making sure that the screws on the physical module fit into the spacers. (See 2 in Figure 2-1).

5Tighten the screws to fix the module in place.

Connecting to	Fast Ethernet TX ports (RJ-45) use CAT-5 STP (shielded twisted pair); Fast
Network Devices	Ethernet FX ports (SC connectors) use multi-mode, fiber cable. The
	connectors TP or TX are configured as MDIX, suitable for direct
	connection to a workstation or other DTE, using a normal,
	straight-through twisted-pair cable. To connect a 7600 Card to another
	10/100BASET switch, you can use either a crossover cable or, if
