The GNSS RF In port should have a primary protector installed to meet the Local Safety guidelines.
Note
• The GNSS RF In coaxial cable shield must be connected to the Facility Equipment Ground through the
chassis. The chassis must have the ground wire connected to the Facility Equipment Ground.
Connecting Ethernet Cables
The Cisco ASR 920 Series 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:
Procedure
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.
