Netfinity 5500 M10 - SCSI Backplane component locations and SCSI Backplane option jumpers

Applicable to: World-Wide

SCSI Backplane Component Locations

The following simplified layout of the SCSI backplane identifies the components. Refer to this figure when you set the jumpers on the backplane.

1 Wide (16-bit) SCSI connector
2 Option jumper block (J10)
3 SCSI hot-swap drive connectors (on reverse side of backplane)
4 Repeater card connector
5 Power connector

SCSI Backplane Option Jumpers
The option jumper block on the SCSI backplane defines the SCSI IDs for hot-swap drives. See the illustration in "SCSI Backplane Component Locations" for the location of the option jumper block.

Table 10 summarizes the settings for the SCSI backplane option jumper block (J10).

Table 10. Backplane Option Jumper Block

Pins

Description

1-2

Reserved.

3-4

Reserved.

5-6

Placing a jumper on these two pins enables SCSI IDs 8-13

7-8

Reserved.

9-10

Reserved.

11-12

Placing a jumper on these two pins reverses the SCSI IDs on the backplane.

Note: The default is no jumpers installed on the J10 jumper block.

Table 11 shows the SCSI IDs that you can use for hot-swap drives.
