Handling A Fixed-Disk Drive - IBM 6150 Hardware Maintenance Manual

Handling a Fixed-Disk Drive
8-4 Service Manual
Read and become familiar with the following fixed-disk drive handling
precautions.
• Do not remove the antistatic bag from the drive until you are ready to
install the drive in the system unit.
• Do not grasp the center part of the fixed-disk drive when you are
handling the drive. The squeezing action could damage the circuit
board. Handle the drive by the frame only.
• Do not drop or lay the fixed-disk drive down roughly, because that
action may permanently damage the drive.
Observe the following general procedures, in addition to the specific
procedures given in Section 4, to protect the drive from static discharges.
1. Lay the fixed-disk drive (still wrapped in its antistatic bag) on a flat
surface near the system unit.
2. Position yourself so you won't have to walk around while exchanging
the drive. This helps prevent the generation of static electricity.
3. Touch a metal part of your system unit with one hand and the antistatic
bag with the other hand. This will place your body, the drive, and the
system unit at the same ground potential, thus preventing an accidental
static discharge.
4. Slide the antistatic bag off of the fixed-disk drive.
5. Handle the fixed-disk drive by the frame only while installing or
removing it. It is recommended that you use both hands to reduce the
chance of dropping the drive.
6. Put the exchanged fixed-disk drive back in the antistatic bag.
