Upgrading the FRE-2 Processor Module
108305 Rev. D 11
5. Gently push down on the module so that the retainers grasp the SIMM,
locking it into place (refer to Figure 9).
When the SIMM is properly inserted, the two tiny vertical black poles on the
SIMM socket should line up with the two holes in the SIMM.
6. Repeat Steps 3 through 5 to install the other 72-pin SIMM in socket SI 4.
7. Install the 30-pin SIMM in socket U85, using the procedure described in
Steps 3 through 5.
When you are finished, sockets SI 3, SI 4, and U85 are populated. Sockets SI 1
and SI 2 should be empty. Proceed to “Attaching the Upgrade Label.”
Upgrading from 16 MB to 64 MB (FRE-2/060 Only)
If you are upgrading a FRE-2/060 processor module from 16 MB to 64 MB, your
upgrade kit contains four identical 72-pin SIMMs and one 30-pin SIMM.
To upgrade the FRE-2/060 processor module to 64 MB:
1. Using Figure 7 as a reference, locate SIMM sockets SI 1, SI 2, SI 3, SI 4,
and U85 on your FRE-2 processor module.
Depending on the current configuration, there will be SIMMs populating
some, or all, of these sockets.
2. Remove any SIMMs currently populating sockets SI 1, SI 2, SI 3, SI 4, or
U85:
a. Pull back on the retainers grasping the edges of the SIMM to release
it.
b. Gently lift up and pull out the SIMM.
3. Holding one of the new 72-pin SIMMs by its edges, turn it so the keyed
(notched) side faces the center of socket SI 3 (refer to Figure 8).
4. Insert the SIMM into the socket at an angle of about 30 degrees from the
vertical.
5. Gently push down on the module so that the retainers grasp the SIMM,
locking it into place (refer to Figure 9).
When the SIMM is properly inserted, the two tiny vertical black poles on the
SIMM socket should line up with the two holes in the SIMM.
