Check for problems on attached devices
Check the following in order to find problems on attached devices:
•LEDs
•Display panels
•Firmware levels
•Operability
Check host versions
Check the following to find problems on attached hosts:
•Operating system version
•Service pack version
•Host adapter version
•Host adapter firmware version
•Host adapter device driver version
•iSCSI driver version
If an update is required, perform the update. For an updated list of supported iPBridge host platforms and host adapters, visit www.attotech.com.

Checking SCSI devices
1Check SCSI devices to make sure they are all set to different SCSI IDs.
By default, the iPBridge SCSI ports use SCSI ID 7 so drives should use IDs 0 through 6 and 8 through 15.
2Check the SCSI device power. Make sure the devices are powering up.
3Watch the drive lights before, during, and after startup. Many drives have term power lights that should be on before startup and turn off when system boots.
4Verify the external terminator is the correct type and does not have damaged pins.
5Check cable integrity. Check the cables for solid connections. Make sure they are screwed down. Inspect cable ends for bent pins.
6If termination is correct, and the problem persists, try drives one at a time with different cables, adding drives and cables until the

problem occurs. This helps pinpoint the drive or cable causing the problem.
7Check with the manufacturer of SCSI device(s) for further troubleshooting methods.
If SCSI devices appear to be working, move on to the iPBridge SCSI port section.
Checking the iPBridge SCSI ports
1Verify the iPBridge has its termination set properly. By default, termination is enabled.
2Either through the ATTO ExpressNAV or CLI, perform a SCSI bus scan on each SCSI port.
Refer to SCSI configuration commands on page 47.
If no devices appear,
3Check the internal cabling of the SCSI device.
LVD SCSI cable lengths are limited to 12.5 meters. Longer cable lengths can cause problems. Internal cabling is also considered when calculating total cable length. For details, refer to Cabling on page iii.
4Some older SCSI devices improperly negotiate with the iPBridge SCSI port. If older devices are
