Appendix B Uninterruptible Power Supply

B.5. Power On

When powering on the subsystem, the UPS must be powered on before the subsystem. To

see how to power on the UPS, please refer to the documentation that came with your

UPS. Note that the power on sequence described in Chapter 4 will be altered. The power

on sequence when a UPS is connected is shown below:

Step 1. Power on the network connection devices (including FC switches).

Bypass this step if you are using a SCSI host subsystem.

Step 2. Power on any expansion/cascaded enclosures connected to the

subsystem.

Step 3. Power on the UPS.

Step 4. Power on the subsystem.

Step 5. Power on the application servers.

Step 6. The subsystem firmware should detect the UPS. To see how to do this

please, refer to the Generic Operation Manual that came with the

subsystem.

NOTE:

A UPS can be connected to the subsystem after the subsystem has been powered on,

but you will have to trigger the firmware to allow the subsystem to detect the UPS.

B.6. UPS Status Monitoring

If a UPS is correctly connected to the subsystem, the status of the UPS will be constantly

monitored by the controller through the COM2 (audio jack) serial port. The status of the

UPS will determine the controller’s write policy, and messages that appear on the LCD

panel and other monitoring devices will keep you informed of the UPS status.
