Tools
■ ESD wrist strap (no hand tools are required to perform this procedure).
Whenever possible, follow ESD procedures.
Procedure
Caution Whenever possible, follow standard ESD procedures and avoid
touching exposed circuitry.
Do not remove a disk or filler from an operating product until you
have the replacement part and are ready to install it. An empty slot
will cause uneven cooling and overheating.
1 Release the disk module from the slot by squeezing the latch tab (see
Figure 57) and pulling the disk module toward you.
Caution Spinning disks generate heat and gyroscopic force.
Wait for a spinning disk to slow down and cool off before
removing it from the product.
WARNING High current available. Avoid touching the midplane or adjacent
drive electronics when removing and inserting disk modules.
2 Pull the disk out of the slot using the extraction handle. Support the disk
module with your other hand around the enclosed side. See Figure 57.
Note Removing disk modules and fillers from right to left improves
access to successive disk modules.
