1.1 Verifying the Fan Unit Alarm Connection to the SCU
Perform Steps Below in the Order Listed
References to common, but differing, parameters between the Total Access
3000 and the Total Access 3010, such as number of slots, will be conveyed
by the convention a/b. The "a" represents the Total Access 3000 parameter
and the "b" represents the Total Access 3010 parameter. For example, the
differing number of access slots in the two platforms, 28 for the Total Access
3000 and 22 for the Total Access 3010, would be displayed "28/22."
1.1.1 Introduction
This procedure details the test steps which must be performed to verify that the Fan
Unit's Alarm Relay contacts have been properly wired to the SCU external alarm
inputs and that the SCU is properly provisioned to indicate a fan unit failure when this
condition is indicated by the fan unit.
This procedure should be performed at installation on each Total Access 3000/3010
shelf that has a Fan Unit installed in the shelf's heat baffle/fiber optic routing tray.
1.1.2 Prerequisite Procedures
Before beginning this procedure, you should have completed the installation tasks
detailed in DLP-711 and provisioned the SCU as indicated in the Shelf Installation
NTP-501.
1.1.3 Tools and Materials Required
• Fuse Extractor (if required by model of fan fuse in use)
To prevent electrical shock, do not install equipment in a wet location or
during a lightning storm.
Electronic modules can be damaged by static electrical discharge. Before
handling modules, wear an antistatic discharge wrist strap to prevent damage
to electronic components. Place modules in antistatic packing material when
transporting or storing. When working on modules, always place them on an
approved antistatic mat that is electrically grounded.
