Step 3. Secure the BBU module to the enclosure. Tighten the two (2) spring

screws as shown above on the back of the BBU module.

Step 4. Once the new BBU module is correctly installed into the subsystem,

the LED should start flashing, indicates the BBU is being charged.

When the BBU is fully charged, the LED will go off.

5.5. Replacing a Failed PSU Module

5.5.1 Notes on PSU Module Maintenance

♦ Two redundant PSU modules: The subsystem comes with two fully redundant, hot-

swappable PSU modules. These modules are accessed from the rear of the

subsystem.

♦ Immediate replacement: When a PSU fails, it should ideally be replaced

immediately. Do not remove the PSU module unless a replacement is readily

available. Removing a PSU without a replacement will cause severe disruptions to

the internal airflow and the subsystem will overheat, possibly causing irreparable

damage to some of the subsystem components.

WARNING!

Although the subsystem can operate using single PSU module, it is not advisable

to run the Rorke Data subsystem with a single PSU module for an extended period

of time.
