Cisco ASR 903 Hardware Installation Guide

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
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.
Note
Follow these steps to connect the cable to a copper Gigabit Ethernet port:
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.
Connecting Cables to SFP Modules
For information on connecting cables to Cisco optical and Ethernet SFP interfaces, see
http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html.
Connecting T1/E1 cables
The physical layer interface for the Cisco ASR 903 Router T1/E1 port is a customer-installed high-density
connector. The high-density connector has thumbscrews which should be screwed into the interface when the
cable is installed.
Patch panels are required in order to connect the high-density interface connectors to individual T1/E1
lines.
Note
Installing the Cable Connectors
16 x T1/E1 Cable Connectors
The 16 x T1/E1 interface module requires a patch cable (see Recommended Patch Panel). One end of the
cable (see the figure below ) has a 100-pin connector that plugs into the T1/E1 interface module. Use the
thumbscrews on either side of the connector to secure the cable to the interface.
