Chapter 1: Appliance Hardware Functions
To Reinstall a Power Supply:
1.
To replace a power supply, reverse the steps above. Press firmly to seat the connector. The power supply
can be fully inserted only in its proper orientation.
2.
Connect an AC power cord.
The Fans
In normal operation, the fans should require no maintenance.
You might need to perform the following tasks:
>
Clean the filter (occasionally)
>
Replace a defective fan (rarely)
CAUTION!
Opening the fan bay causes a system tamper event
We recommend that you use scheduled system maintenance downtime for this activity, as it
will temporarily disrupt your client's access to your HSM partitions. If the system detects a
tamper event, the HSM stops responding until you reboot (
sysconf appliance reboot
), or
until you use the Stop/Start switch on the appliance rear panel.
Cleaning the Filter
The ventilation grille, located to the right, on the appliance front panel, is secured in two parts, by two screws - a
knurled, captive thumb-screw, and a Torx T8 screw. The knurled screw can be fastened or released without
tools. It secures the lattice screen that in turn retains the mesh air filter.
While we recommend controlled-atmosphere environments for greatest longevity and reliability of the
equipment, we recognize that some environments might include some dust in the air. The mesh filter traps
larger particulate matter before it can be drawn into the interior of the appliance. In less-than-perfect non-
clean-room conditions, the mesh might accumulate a buildup of dust, and should be cleaned occasionally for
best cooling airflow into the equipment.
NOTE
Accessing the air filter mesh in front of the fans (using the thumbscrew to open the
retaining grille) does not cause a tamper.
To clean the filter:
1.
Twist the knurled knob counter-clockwise until it no longer secures the airflow lattice. The lattice is anchored
at its left end by two tabs, and can be easily pulled off the appliance, once the knurled retaining screw is
loosened. Do so.
