messages. The relay contacts can be controlled through any appropriate third-party relay controller. The
open/close configuration is an option controlled in IOS.
Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect
the alarm ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded
and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly
must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are
designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE)
and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient
protection in order to connect these interfaces metallically to OSP wiring.
Only Pins 1, 2, 4, 5, and 8 are available for customer use. The remaining pins are for Cisco manufacturing
test, and should not be connected. Use a shielded cable for connection to this port for EMC protection. Table
5-6 summarizes the pinouts on the alarm port in Troubleshooting.
Step 1 Attach an RJ45 cable to the alarm port.
Step 2
Attach the other end of the RJ45 cable to the relay controller.
