HP StoreEver MSL Tape Libraries - Manual (Page 44)

Figure 31 Aligning the Extender tab in the Library slot
.
The tab on the Extender must be inserted in the slot on the master Library, as shown in Figure 31 ,
for the Extender to seat properly in the connector in the master Library. If the tab is under or to the
left of the bracket, the electrical connection will not be completed.
• The master and lower Libraries have the current firmware versions.
If Library Extender status LED (2), is flashing:
• The Library Extender may be initializing. Check the OCP for status messages and wait a few
minutes for the initialization process to complete. Initialization can take up to 15 minutes.
• The Library Extender has failed with a hard error. See the master Library log to find the error code.
If the lower Library connection status LED (3), is not green, verify the following:
• The lower Library is powered on.
• If the lower Library is an MSL4048, its power supply status is Good .
• Extended mode is enabled in the lower Library.
• The rack rails are straight and the front bezel screws attaching both Libraries to the rack are secure.
The back planes of the two Libraries should be aligned in the same plane. If the master Library is
set further back the plug on the Extender might not reach the connector on the lower Library.
• The master and lower Libraries have the current firmware versions.
The Library Extender cycle test
The Library Extender cycle test verifies that the Library Extender can transfer cartridges between
Libraries. The Library Extender cycle test moves the first available cartridge in the master Library to
the lower Library and back, exercising the robotics in both Libraries and the Extender, with cartridge
exchanges in both directions. When the test is complete, the cartridge is returned to its original slot.
The Library Extender cycle test is executed from the RMI or OCP.
The wellness test
The wellness test exercises all Library and tape drive hardware, except the external connections, and
is useful for verifying that a device is working correctly. The wellness test requires operator interaction
with the mailslot so cannot be initiated from the RMI.
