3–5. Installing an EXB-PCM
A maximum of eight EXB-PCM boards can be installed
simultaneously.
If you are installing a single EXB-PCM, it will function
correctly whether installed in either slot. For ease in
installation, you may wish to use EXB-PCM slot 1 first.
You must leave the AC/AC power supply disconnected
until you finish the entire process of removing the lid,
installing the option board or memory, and reattaching
the lid.
1
Verify the location where the EXB-PCM will be installed.
(
☞
diagram below)
2
Remove the EXB-PCM from its bag.
3
The notched side of the EXB-PCM is PIN 1. Install the
EXB-PCM with its PIN 1 side aligned with the PIN 1
mark (
) of the slot.
The EXB-PCM slots and the DRAM SIMM slots are
shaped identically. Be careful not to install a board in
the wrong slot.
4
At a slant, press the EXB-PCM firmly all the way into the
slot, and raise it to the vertical position until the catches
of the slot click into the locking holes of the EXB-PCM.
When doing so, pressing the catches of the slot apart to
the left and right will help the board go in smoothly.
5
Reversing the procedure by which you removed cover,
re-attach the cover.
6
When all steps have been completed, turn on the power
and make sure that the EXB-PCM has been installed cor-
rectly. (

“Checking after installation”)
Removing an EXB-PCM/DRAM SIMM
Spread the catches of the slot apart to the left and right, and
(after removing the stoppers from the catches) tilt the EXB-
PCM/DRAM SIMM and pull it out.
When you spread the catches of the slot apart, the EXB-
PCM may pop out vigorously and fall into an opening
(inside the instrument). Please be careful.
