*The head brush error recovery procedure (ERP) is intended to prevent a permanent read
or write error by removing debris that might have accumulated on the read or write head.
In order to brush the head, the tape must be unthreaded to expose the head. This forces
the loader to be cycled to enable re-thread. During the loader cycling, the back of the
cartridge will temporarily extend beyond the front of the bezel. Extension of the cartridge
is problematic in some automation environments, so you have the ability to disable this
function. If the head brush ERP is disabled, the drive will immediately report the
permanent error instead of activating the head brush ERP.
Mount the drive in an enclosure or server
When mounting the drive:
v
Use an appropriate screw length.
v
Make sure that no objects such as screw heads, cables, or adjacent devices, are
pressing against the frame.
v Do not obstruct the ventilation slots at the rear of the drive.
v
Allow sufficient space for accessing the drive's front panel controls.
To mount the drive into an enclosure:
1.
Remove the cover of your enclosure (refer to the instructions in the
documentation provided with your enclosure).
2. Place the drive into your enclosure so that the tape load compartment of the
drive faces the tape load compartment of the enclosure.
3. Insert two M3 screws into the mounting holes of the two side brackets located
on the left and right sides of the chassis.
Attention: When the mounting screws or drive rail prongs are inserted into the
drive, they must not extend farther than 2.5 mm (0.098 in.) inside the chassis.
Otherwise, they might damage the drive.
