Step 5 Reconfigure and reboot the connected device if necessary.

Step 6 Repeat Steps 1 through 3 to connect each 100BASE-FX port.

Connecting to an LRE Port

Depending on the switch model, you can connect the LRE port to either 12 or 24 Cisco 575 LRE customer premises equipment (CPE) devices through a patch panel. If telephone services, such as voice or integrated services digital network (ISDN), use the same cabling as LRE traffic, you must connect the LRE to a plain old telephone service (POTS) splitter.

Note If no other telephone services travel on the same wiring as LRE traffic, the LRE switch connects directly to a patch panel.

Connecting the LRE port to a patch panel or POTS splitter requires a male-to-male RJ-21 cable, category 3 or above.You can order RJ-21 cables from your cable vendor, or you can order these cables from your Cisco sales representative:

•CAB-5-M120M120-5 (Category 5 cable with 90-degree, male-to-male RJ-21 connectors)

•CAB-5-M180120-5 (Category 5 cable with 120-degree, male-to-male RJ-21 connectors)

The screws you need to secure the cable to the switch are shipped with the cable. Contact your Cisco sales representative for more information.

To connect the LRE port to a patch panel or POTS splitter, follow these steps:

Step 1 Connect one end of a wiring trunk cable to the RJ-21 connector of the LRE port on the switch. (See Figure 2-19.)
