PERFORM INITIAL FUNCTIONAL CHECK OF THE
INTEGRATED FAN/POWER SUPPLY ASSEMBLY
Summary:
This procedure covers initial power-up of an Integrated Fan/Power Supply
(HW-PSFAN-x-xxx), and how to interpret and respond to initial front-panel LED indications on
the assembly.
Note:
In case of field failure, modules shall be replaced as a unit. No field servicing of
the individual boards or components comprising the HWX system or modules shall be
required. Failure to comply could result in voiding of the equipment warranty.
Warning:
To prevent electrical shock, never work on electrical equipment in a wet
location or during a lightning storm.
1. Obtain the following tools and equipment:
ESD wrist strap
Digital voltmeter with test leads
Caution:
Electronic equipment can be damaged by static electrical discharge. When
handling the Integrated Fan/Power Supply, always follow Electrostatic Discharge
(ESD) protection practices. Wear a grounded wrist strap when you touch a unit. Use
antistatic packaging when transporting or storing units. When working on a unit,
always place it on an approved, electrically grounded, antistatic mat.
2. Place the ESD wrist strap on your wrist and snap the ground wire to the wrist strap.
Plug the ground plug into a grounded ESD jack.
3. Connect the female end of the power cord to the IEC connector at the rear of the unit;
plug the male end of the cord into an active AC power outlet. Depress the
I
(on) side
of the units power on rocker switch to apply -48 VDC and air flow to the shelf.
4. Read the below listed notes, then proceed to
Table 503-1, Fan/Power Supply Fault
Diagnostic/Probable Cause
, to verify normal assembly operation.
Note:
Verifying normal operation and fault diagnostics portion of this procedure is set
out in a sequential table format.
Module LED Indications

guide to fault isolation through module LED analysis. The LED indications are shown
in actual module layout positions, using the following legend:
