Troubleshooting
7.1
Device is not detected or recognized.
Make sure you have a known good set of HIB card (host and target cards), cables and backplane.
1.
Check the Dip switch settings on each card. Make sure each card is properly configured.
2.
Re-seat the host and target cards. Turn the power OFF before re-seating the HIB cards.
3.
Re-seat the link cable(s). Ensure that the host system and expansion units are completely powered down when reseating the cables.
4.
Unplug all power from the host computer and expansion unit and reconnect it. Turn the expansion unit ON first before the host
computer.
5.
If you have replaced the link cables, OSS target and host cards and still experiencing the problem, try a different known-good
computer.
6.
Try another expansion unit or replace the backplane.
7.
Send the OSS unit / hardware to OSS for evaluation / analysis and repair.
7.2
Broken OSS-518 Board
1.
If you received a brand-new DOA (Dead on Arrival) board, please contact OSS to RMA board and request for a replacement.
2.
If you have an out of warranty board, please contact OSS Sales team and buy a new replacement board.
•
Standard warranty is 1 year unless you have an SLA or extended warranty coverage.
3.
If you purchased a second-hand / used board and it is broken, please contact OSS Sales team to buy a replacement.
•
Note: Purchasing a second-hand / used product is not covered under warranty.
7.3
Intermittent start up issue and PCIe cards are not getting recognized.
If you are using a 4UValue chassis that has two backplanes and it is having issue starting up and the GPUs or PCIe cards are not detected, do the
following steps:
1.
Completely shut down the expansion unit and host server. Physically disconnecting the power cord from the expansion unit and
computer.
2.
Remove all the PCIe cards from the expansion unit.
3.
Disconnect the OSS link cables from the expansion unit and host computer.
4.
Reseat the OSS Target card and Host card.
5.
Reconnect all the OSS link cables to the Host and Target cards.
6.
Do not install any PCIe cards yet.
7.
Reconnect the power cord to the expansion unit and computer.
8.
Turn ON the computer and the expansion unit will automatically power ON.
If the unit powers ON, do the next steps:
9.
If the expansion chassis powers ON properly, that's good. Next is to shut it down.
10. Turn OFF the computer and this should power down the 4UV chassis.
11. Disconnect the power cord from the back of the 4UV chassis.
12. Disconnect the power from the computer.
13. Install one PCIe card on the backplane. If you have two backplanes, one PCIe card per backplane.
14. Reconnect the power cord to the expansion unit and computer.
15. Turn ON the computer, expansion chassis will automatically power ON!
16. Boot the computer all the way up and check if the PCIe cards are detected.
17. Install the remaining PCIe cards. Repeat the same steps (from step 10 to 15)
