Component check

Use this procedure to check system components. For
more information on the commands used in this
procedure, refer to CLI provides ASCII-based
interface on page 31.

Checking SCSI devices

1 Check 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.
2 Check the SCSI device power. Make sure the
devices are powering up.
3 Watch 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.
4 Verify the external terminator is the correct type
and does not have damaged pins.
5 Check cable integrity. Check the cables for
solid connections. Make sure they are screwed
down. Inspect cable ends for bent pins.
6 If 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.
7 Check 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

1 Verify the iPBridge has its termination set
properly. By default, termination is

perform a SCSI bus scan on each SCSI port.

2 Click on the Status page and view the
information on the product version.
3 If an update is needed, download the update
from www.attotech.com.
Refer to Updating firmware
If no devices appear, re-check SCSI cables and
termination. If garbage information appears,
the problem is most likely a bad SCSI cable or
termination.
3 Check 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.
4 Some older SCSI devices improperly negotiate
with the iPBridge SCSI port. If older devices are
not showing up, contact your service
representative.
5 If all devices appear, invoke the ScsiTargets
command several times on each SCSI port to
verify that the devices can be seen. If devices
disappear then appear again, the problem is
most likely a SCSI cable. For information on the
ScsiTargets command, refer to
configuration commands
If all devices appear and remain, move to the
iPBridge internal configuration section.
When changing any setting on the iPBridge the
configuration must be saved by using either the
saveConfiguration CLI command or through the
ATTO ExpressNAV interface.

Checking the serial port

1 Verify you have the correct settings and that
your terminal is configured to:
• Baud rate: 115200
• Data bits: 8
• Stop bits: 1
• Parity: off
• Flow control: None
2 Verify that your serial cable is less then two
meters in length.
