¹ As per NEBS GR-63-CORE, short term refers to a period of not more than 96 consecutive hours and a total of not more than 15 days in one year (This refers to a total of 360 hours in any given year, but not more than 15 occurrences during that one year)

In the front fan section, a fan failure means that one of the fans on both fan trays stopped working (5 out of 6 fans are working).
In the rear fan section, a fan failure means that one of the fans on both fan trays stopped working (1 out of 2 fans are working).

Replace a failed fan tray as per the replacement procedure within the OIR time limits.

Cable Specifications

The Cisco NCS 1020 has the following cable specifications:

AC and DC power cables that you have ordered.

AC chassis—while ordering for an AC chassis, select the power cable type (straight, 90-degree, or jumper) and P1 connector (NEMA or CEE). Based on your choice, you will get a pair of 90 degree, straight, or jumper cables with NEMA or CEE connector for each PSU.
