To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect
the ToD 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.
Warning
For more information about GPS-port pinouts, see the
Troubleshooting
section.
Note
Connecting Ethernet Cables
The Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router interface modules support RJ-45
and Ethernet SFP ports. For instructions on how to connect cables to Ethernet SFP ports, see
the Connecting
Cables to SFP Modules
section.
The RJ-45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair (UTP)
cables. Cisco does not supply Category 5 UTP cables; these cables are available commercially.
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the Gigabit Ethernet 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.
Warning
Follow these steps to connect a cable to a copper Gigabit Ethernet port:
SUMMARY STEPS
1.
Confirm that the router is powered off.
2.
Connect one end of the cable to the Gigabit Ethernet port on the router.
3.
Connect the other end to the BTS patch or demarcation panel at your site.
DETAILED STEPS
Step 1
Confirm that the router is powered off.
Step 2
Connect one end of the cable to the Gigabit Ethernet port on the router.
Step 3
Connect the other end to the BTS patch or demarcation panel at your site.
