HP StoreEver MSL Tape Libraries - Manual (Page 8)

The LTO-4 tape drive must have the following or later versions of tape drive firmware:
Fibre Channel SAS Parallel SCSI
Not Applicable U26W W22W Ultrium 1760
H44W Not Applicable B45W Ultrium 1840
To find the version of firmware on your tape drive, see “Verify your autoloader or library firmware
version” (page 18) .
NOTE: With the above LTO-4 tape drive firmware revisions, the autoloader or library will NOT
allow LTO-3 media in LTO-4 tape drives when encryption is enabled with the encryption kit. Always
ensure that your tape drive has the most recent firmware version. You can download tape drive
firmware files from the HP Support website at
http://www.hp.com/support .
Access to the USB port
To use the key server tokens included in the encryption kit, the USB port on the back of the
autoloader or library must be accessible. Only the rear USB port on the MSL6480 may be used
for the key server token. On some MSL2024 and MSL4048 libraries you might need to remove
the silver tape covering the USB port.
