Connecting Cables To Sfp Modules; Installing And Removing Sfp Modules - Cisco NCS 560-4 Hardware Installation Manual

Connecting Cables to SFP Modules

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:
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.

Installing and Removing SFP Modules

The Cisco NCS 560-4 Router supports a variety of SFP modules, including optical and Ethernet modules.
For information on how to install and remove SFP modules, see the documentation for the SFP module at
http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html
For information about inspecting and cleaning fiber-optic connections, see
http://www.cisco.com/en/US/partner/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml
Caution
We recommend that you wait 30 seconds between removal and insertion of an SFP on an interface module.
This time is recommended to allow the transceiver software to initialize and synchronize with the standby
RSP. Changing an SFP more quickly could result in transceiver initialization issues that disable the SFP.
