Verifying Fan Module Alarm
Connection to the SCU

INTRODUCTION

This procedure provides step-by-step instructions to verify the Fan Module's alarm relay
contacts are properly wired to the System Controller Unit (SCU) external alarm inputs. This
procedure also verifies that the SCU is properly provisioned to indicate a Fan Module failure
when a failure condition is indicated by the Fan Module.
This procedure should be performed after the installation for each MX2820 shelf that has a
Fan Module installed in the shelf's heat baffle.

PREREQUISITE PROCEDURES

The following procedures must be completed before verifying fan unit alarm connection to the
SCU. If necessary, refer to the appropriate documentation before proceeding.
• "NTP-005, SCU Provisioning (System Management)"
• "NTP-006, SCU Provisioning (System Security)"

TOOLS REQUIRED

• Fuse Extractor (if required by model of fan fuse in use)
To prevent electrical shock, do not install equipment in a wet loca-
tion or during a lightning storm.
