Replacing the SCC-LTM/RLTM

If you need to replace the SCC-LTM or SCC-RLTM, note the configuration of installed network cabling before you disconnect any cables. This includes cabling to the following ports:

•Local 10/100 Mb/s Ethernet ports

•Console port

•HSSI port

•Alarm port

•T1 ports or E1 ports

•Optical ports

You will need to reinstall this cabling on the replacement SCC-LTM/RLTM.

Caution: Before removing the SCC-LTM or SCC-RLTM, you must first remove the corresponding SCC-SMs. The LTMs and RLTMs are not hot-swappable (that is, you cannot change them while the system is running).

Removing the SCC-LTM or SCC-RLTM

To remove the SCC-LTM or SCC-RLTM, follow these steps:

Step Action

1Turn off power by turning off the switches on the PDU.

2Disconnect any cables attached to the SCC-LTM/RLTM.

Note: If you are using the alarm connections, you can leave the alarm wiring in place by removing the alarm connector block from the SCC-LTM/RLTM. Use a 1/8-inch flat-tip screwdriver to remove the alarm connector block.
