DR009 - Resolve AC Failure
This DR provides customer resolution steps for T024 on page 222.
Problem: The facility AC power appears to have failed on a power supply. This can be the result of the facility
power actually being off, the power switch on the power supply being turned off, or an actual failure in the
power supply. A disconnected module terminator or module-to-module cable with bent or broken pins can
also cause this issue.
1 Check the facility AC power, and make sure the power supply is properly seated, and the power switch
is on.
2 Inspect all module terminators for any broken or bent pins.
3 If the library consists of multiple modules, inspect all module-to-module cables for any broken or bent
pins.
4 Contact Service for assistance.
5 You have three options:
a. Select Close to close the ticket now.
b. Select Exit to leave the ticket open for future troubleshooting.
c. Select Back to return to the Diagnostic Resolution.
DR010 - Termination and Connectivity Diagnostic
This DR provides customer resolution steps for T062 on page 258.
Problem: The library requires two terminators to be plugged into two specific ports on the rear of the library
in order to automatically detect its configuration. In a multi-module system, these terminators are placed in
the expansion modules at the very top and bottom of the vertical stack. In addition, cables must connect all
modules together.
1 Are the terminators and all module-to-module cables plugged in properly?
If NO: Power down the library, connect the cables in, and power the library back on. When the library
powers up, it should detect the presence of the cables and terminators and properly configure itself.
Select Continue before you turn off library power.
2 When you can answer YES in step 1: Place both terminators into the CM to begin isolating the problem.
You may back up or proceed with the self test.
• Self test failed – Inspect the module connectors and terminators for bent or broken pins. Contact
Service to order replacement terminators.
• Self test passed – The current library configuration is working properly. Continue to isolate the
failure by plugging the terminator into the next upper expansion module and connecting the
modules with the module-to-module cable. After the terminators and cables are installed, perform
the self test again. If there is no additional upper expansion module, select the Next button.
• Self test failed – Inspect the module connectors and module-to-module cables for bent or
broken pins. Contact Service to order a replacement cable or expansion module.
• Self test passed – The current library configuration is working properly. Continue to isolate the
failure by plugging the terminator into the next lower expansion module and connecting the
modules with the module-to-module cable. After the terminator and cables are installed,
perform the self test again. If there is no additional lower expansion module, select the Next
button.
