6.2.6Step 6 Set SCSI Terminator Power

J17 and J18 control the termination power setting for the MegaRAID 320-2 SCSI channels, as explained in Section 6.2.4.6, “J17/J18 SCSI Bus Termination Power,” page 6-8. By default (jumper installed on pins 1 and 2 of J17 and J18), the PCI bus supplies termination power.

See the documentation for each SCSI device for information about enabling TermPWR.

Important: The SCSI channels need Termination power to operate. If a channel is not being used and no auxiliary power source is connected, change the jumper setting for that channel to supply TermPWR from the PCI bus.

6.2.7Step 7: Install Battery Pack (Optional)

You can install a battery pack on the RAID controller using the J10 connector. The battery pack provides emergency power to the MegaRAID 320-2 SCSI controller in the event of power failure.

•LSI Logic Part Number: BAT-NIMH-3.6-02

•Description: Battery, NIMH, 3.6 V, 600 mA onboard battery pack with mounting brackets

You install the battery pack by attaching it to the controller board through the backside of the board, using the three holes in the board. Then connect the three wires from the battery pack to J10, the external battery connector (the black wire connects to pin 1). Figure 6.7 shows an installed battery pack (upper right corner).
