Replacing a Faulty BBU

i

NOTICE!

The BBU is hot-swappable and can be replaced while the subsystem is running. However, a new module will only be recognized after a subsystem reset. Carefully select the time when the reset will be made in order to minimize the overall disruption to service.

i

To replace a faulty BBU, please follow these steps:

1.Remove the faulty BBU module from the chassis. The BBU module is secured to the chas- sis with two (2) spring screws. These screws must be loosened. To loosen, turn the screws counterclockwise.

2.Install the new BBU module. After the faulty BBU module has been removed, the new BBU module can be installed. To do this, align the BBU module with the empty slot, and then gently push the BBU module into the slot.

3.Secure the BBU module to the enclosure. Tighten the two (2) spring screws on the back of the BBU module.

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.

NOTICE!

The life expectancy of a BBU is approximately 500 cycles. Follow the procedures above to replace an old BBU with a new BBU in order to maintain fault-tolerant subsystem functional- ities.

Notes on PSU Module Maintenance

•

•

•

Two redundant PSU modules: The subsystem comes with two 350W, 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 sub- system will overheat, possibly causing irreparable damage to some of the subsystem components.

PSU bracket: Each PSU module is permanently mounted in a two-level steel bracket, cre- ating a single unit. The PSU is located in the upper level and a removable cooling fan module is mounted in the lower level.

CAUTION!

Although the subsystems can operate using single PSU module, it is not advisable to run the RAID subsystems with a single PSU module for an extended period of time.

6.5.2

Replacing the PSU Module

 

To replace a PSU, please follow these steps:

 

1.

Turn off the PSU and remove the power cord: Turn of the power switches located on the

 

 

right side of each power supply module.

 

2.

Once the power switches have been turned off, remove the power cables that connect

 

 

the subsystem to the main power. The power connector is found on the left side of each

 

 

power supply module.

 

3.

Remove the retention screw: After the power cable has been removed from the power

 

 

connector, remove the retention screw at the upper right side of the PSU rear-end panel.
