Etsi Power And Ground; Ntp-L12 Installing Power And Ground To The Ncs 2006 Shelf - Cisco NCS 2006 Hardware Installation Manual

ETSI Power and Ground

The DC power modules have –48 VDC or –60 VDC #8 dual-hole lug power terminals for. The terminals are
labeled RET and –48 V or –60 V on the DC power modules.
When the NCS 2006 shelf is powered at –60 VDC (nominal), only the TNC, OPT-AMP-C, OPT-AMP-17-C,
Note
OPT-EDFA-17, and OPT-EDFA-24 cards, and the NCS2006-ECU-60 can be installed.
We recommend the following wiring conventions, but customer conventions prevail:
• Red wire for battery connections (–48 VDC or –60 VDC).
• Black wire for battery return connections (RET).
• The battery return connection is treated as DC-I, as defined in Telcordia GR-1089-CORE, Issue 6.
The ground lug must be a dual-hole type, UL Listed, CSA certified and rated to accept the #6 AWG cable.
Two ground posts with two M5 nuts are provided on the NCS 2006 to accommodate the dual-hole lug.
Only use the power cables shipped with the NCS 2006 shelf.
Note
ETSI Power and Ground
The NCS 2006 for ETSI has –48 VDC or –60 VDC power connectors (DSUB for DC power module) on the
DC power module. For redundant DC power feeds, install both the DC power modules and use the two power
cables shipped with the NCS 2006 and one ground cable. For a a DC power supply, the fuse rating must not
exceed 40A.
For redundant AC power feeds, install both the AC power modules and use the two power cables (right and
left cables) shipped with the NCS 2006 and one ground cable. For an AC power supply, the fuse rating must
not exceed 10A, 15A, or 20A. For North America, the branch circuit protection must be rated 20A. The
overcurrent/short circuit protection must be in accordance with local and national electrical codes. The voltage
rating value for AC power ranges between 100 VAC to 240 VAC depending on the standards in various
countries. This product is intended for use on the TN and TT power systems.
Only use the power cables shipped with the NCS 2006 shelf.
