Important information for IBM ServeRAID:

If you are using a ServeRAID software version earlier than the Version 3.50, the View Configuration screens might show SCSI IDs or bay numbers. If the data shown on the View Configuration screen begins with 0, it denotes SCSI IDs. If the data shown on the View Configuration screen begins with 1, it denotes bay numbers.

Netfinity EXP300 bays

The following sections describe the hot-swap CRUs, the switch card bay, and the bridge card bay on the Netfinity EXP300 expansion unit.

With the hot-swap features of the Netfinity EXP300, you can remove and replace hard disk drives, power supplies/fans, and ESM boards without turning off the expansion unit. Therefore, you can maintain the availability of your system while a hot-swap device is removed, installed, or replaced.

Hot-swap drive bays

The following illustration shows the location of the hot-swap drive bays accessible from the front of your expansion unit. The Netfinity EXP300 supports up to 14 IBM Ultra160 SCSI or Ultra2 SCSI hard disk drives. These drives come pre installed in a drive tray. The drive and tray assembly is called a drive CRU (customer replaceable unit). You can install the drive CRUs in the 14 drive bays on the front of the expansion unit.

In the following figure, seven of the 14 bays contain drive CRUs, and seven bays contain filler panels. To maintain proper cooling within your expansion unit, always keep a filler panel in each drive bay that does not contain a drive CRU. For information on installing and replacing drive CRUs, refer to “Working with hot-swap drives” on page 17.

Attention: Never hot-swap a drive CRU when its green activity light emitting diode (LED) is flashing. Hot-swap a drive CRU only when its amber fault LED is lit (not flashing) or when the drive is inactive with the green activity LED off (not flashing).

Bridge card bay

The bridge card is accessible from the front of the unit. You can replace the bridge card CRU but you must turn off the expansion unit before doing so. Refer to “Replacing a bridge card” on page 22 for step-by-step instructions.
