Installing a Module
Attention:
v Disk drive modules are electrostatic-discharge (ESD) sensitive. Use the tools and
procedures defined by your organization to protect such parts. See also “Electrostatic
Discharge” on page xi.
v Disk drive modules are fragile. Handle them with care, and keep them well away
from strong magnetic fields.
v Any slot that has no disk drive module installed must contain a dummy disk drive
module. The dummy module ensures that the correct airflow is maintained around
the disk drive modules in the other slots. If a slot remains empty, overheating might
occur.
Notes:
1. Unless you have a particular reason to do so, do not switch off the using system or
the 2104 when installing disk drive modules or dummy disk drive modules.
2. The diagrams in these instructions show a 2104 Model DU3. The procedure for a
2104 Model TU3 is the same, except that everything is turned through 90 degrees.
