Installing the Cisco ASR 903 Router
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
Warning
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.

Note
Connecting Ethernet Cables
The Cisco ASR 903 Router interface modules support RJ45 or SFP Ethernet ports. For instructions on
how to connect cables to Ethernet SFP ports, see
The RJ45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair
(UTP) cables. Cisco Systems does not supply Category 5 UTP cables; these cables are available
commercially.
Warning
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.
Note
When installing the cabling to the RSPs, we recommend that you leave a service loop of extra cabling
sufficient to allow for fan tray removal.
Follow these steps to connect the cable to a copper Gigabit Ethernet port:
Confirm that the router is powered off.
Step 1
Connect one end of the cable to the Gigabit Ethernet port on the router.
Step 2
Connect the other end to the BTS patch or demarcation panel at your site.
