Connecting Ethernet Cables
The Cisco ASR 914 Router interface modules support RJ45 or SFP Ethernet ports. For instructions on how
to connect cables to Ethernet SFP ports, see the Connecting Cables to SFP Modules section.
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.
