Power Line Filter Option
An external DC power line filter option is available and must be installed with an INU/
INUe for NEBS compliance. It ensures Eclipse meets EMI requirements specified
within Telcordia GR-1089-CORE, Issue 4, June 2006.
It is 1RU tall and 140mm wide (5.5”), and is supplied as a kitset comprising the filter
unit, bracket for left or right side rack mounting, and a short 2W2-to-2W2 cable for
connecting the filter unit to the NCC or NPC -48 Vdc inputs.
• Where an NPC is fitted, two filter units are required, one for the NCC, the other for
the NPC.
• The standard power cable supplied with an INU or NPC is re-used as the power input
cable for the filter unit.
