Preparing for Maintenance

Ensure ESD Protection

The repair environment for the library must be free of conditions that could
cause electrostatic discharge (ESD). To protect the library from ESD, follow these
procedures when repairing or testing the library:
Place a static protection mat on the work surface used while removing and
installing library components. Use a 1-megaohm resistor to ground the static
protection mat.
Wear a static protection wrist band whenever you handle library components that
have been removed from their antistatic bags. Connect this wrist band to the static
protection mat or to other suitable ESD grounding.
Keep all components in antistatic bags when not in use.

Gather Tools and Supplies

You must have the following to complete this procedure:
A #2 Phillips screwdriver
A new drive from Spectra Logic
Note:
After removing the new drive from its packaging, keep the packaging to
return the old drive to Spectra Logic.
If there are no empty drive bays in your library, you must install a new
DBA to accommodate additional drives. Backups cannot continue while
you install the new DBA and drive(s). Refer to the Spectra T200, T300,
T680, and T950 DBA Installation Instructions for information.

Continue or Stop Backups

Spectra T200, T380, or T680 Use the following guidelines if you are installing or
replacing a drive in a drive bay assembly (DBA) already in the library.
QIP-attach drives – Backups running to all other drives in the library (or
partition) can safely continue while you install a new drive or replace an
existing one.
Direct-attach SCSI drives (Spectra T200, T380, T680) – If multiple direct-
attach SCSI drives are daisy-chained on the same SCSI bus, adding or removing
a drive interrupts communications on the bus. Stop backup operations to all of
the drives in the daisy chain. Spectra Logic recommends shutting down and
powering off the host computer before replacing a drive. The T950 does not
allow direct-attach drive configurations.
