Solution 1965432.1 : SL3000 - HBQ: Rail Terminator, Error 5010, 5070, Loss of bot – HBC Communication

Applies to:

Sun StorageTek SL3000 Modular Library System - Version All Versions and later
Information in this document applies to any platform.

The HBQ card is the main part of the rail terminator.
There are two terminators in a single SL3000 library.
One terminator is placed on each end of the rail.
Provides matched impedance termination for the signal interface.
Critical for maintaining signal quality.

Symptoms

HBQ: Rail Terminator, Error 5010, 5070, Loss of bot – HBC Communication

Cause

Bad signal quality
Terminator failure can result in missed service interrupt interval and loss of bot – HBC communication.

Solution

Troubleshooting Techniques:

Look for 5010 or 5070 errors on track/tracks. If these errors are found in the log for normal motion (not move-and-push), check track alignment and rail termination.
Run the command 'stats network' from Command Line Interface (CLI) to obtain network statistics
Determine from byte errors or frame overruns if there's a network issue on the rail
Check for a loose or improperly installed terminator connector.
Look for a broken connector
Replace terminator
