Replacing SIMMs
I-6
Total memory varies and depends on the type of SIMM installed.
To replace the SIMM, follow these steps:
1.
Locate the SIMM socket at location U21 on the circuit board.
Locate socket U21 (see Figure I-3). Socket U21 is a "tilt-down" SIMM
socket—you insert the SIMM into the empty socket vertically and then tilt
the SIMM back until it snaps into the socket.

CAUTION: If you do not wear a discharge leash to free yourself of static
before touching the circuit board or the SIMM, free yourself of static by
touching the metal of the chassis before handling the NMM and the SIMM.
2.
Remove the SIMM that is already installed in the socket
(see Figure I-4).
