To prevent damage when you are working with ESD-sensitive parts, observe the following instructions,
and the instructions that are printed on the ESD mat. The following instructions are in addition to all the
usual precautions:
• Ensure that the device power is Off (see “Powering the device ON and OFF” on page 183).
• Put on the ESD grounding wrist strap (
1
) before the ESD-sensitive part is touched. This strap has a high
resistance (1 megohm) resistor in series with the grounding clip (
4
). Use of the ESD grounding wrist
strap is not dangerous to you. It discharges the static electricity from your body. Connect the clip to the
flex ground strap of the gate to the frame. Keep on the strap while you are inserting or removing a logic
card or handling any ESD-sensitive part.
• Keep ESD-sensitive parts in their special ESD shipping bag until ready for installation.
• Do not place ESD-sensitive parts on any machine cover or on a metal table. If you must put down the
ESD-sensitive part for any reason, place it inside its protective shipping bag or on the ESD grounded mat
that is provided in the ESD kit. (Large metal objects can be discharge paths without being grounded.)
• Prevent ESD-sensitive parts from being touched by other personnel.
• Reinstall all covers when not working on the machine.
• Be extra careful when you are handling ESD-sensitive parts during a period of cold-weather, building
heating. Heating of cold air lowers the relative humidity, which increases the static electricity.
Cleaning the operator bezel
Activities such as completing a drive canister installation and some errors that display might require you
to clean the operator bezel. See the 3592 Drive Operator Guide for procedures.
This procedure requires the following items:
• Tape unit cleaner, if available. This cleaner is the only approved cleaning solution for the 3592 drive. You
also can use water.
• Clean, lint-free cloth
Attention:
• Do NOT spray or apply cleaner or fluids directly to the internals of the drive or a tape cartridge.
Doing so damages sensitive parts and mechanisms!
• Do not allow any liquid to wick into a tape cartridge.
• A damp cloth might work better than a dry cloth by reducing the risk of creating a static electrical
charge that can damage data on a tape cartridge.
1. Apply only enough water or tape unit cleaner to dampen a lint-free cloth, but do not apply liquid
directly to a component or the drive.
2. Gently wipe the front of the bezel by using the damp, lint-free cloth.
Power problems MAP
This MAP helps you isolate power failures.
Notes:
• See Chapter 8, “Locations, checks, adjustments, removals, and replacements,” on page 251 for power
supply procedures.
• See “Power supplies” on page 32 for a description of 3592 power.
• See “Redundant power” on page 35 for a description of redundant power.
• See “Power supplies” on page 32 for the location of the AC LED and the DC LED on the power supply.
• Unless otherwise directed, run Verify Fix/Diag from the CE Options menu to test the drive after a FRU
replacement.
