System Setup and Configuration
3.1 CPU and Memory Module Order
Note
Two cables connect to the H3604 console module: a ribbon cable which
connects to the CPU module; and a four-pin power harness connects to
a power harness module (also known as the power board H3604) which
plugs into the backplane. The power harness module is located directly
to the right of the CPU module.
2. Install the module(s) starting with the first empty slot, which is located on
the right side of the power harness module. The power harness module is
located between the CPU module (slot 5) and the first memory module (slot
4).
The memory module(s) must be installed in adjacent slots with no empty
slots between. Slots 12 through 6 are Q–bus slots, or slots 10 through 6 are
Q–bus slots and slots 12 and 11 are optional DSSI slots; slot 5 is the CPU
slot; and slots 4 through 1 are the memory module slots.
3. Make sure the ratchet handles on the memory module are on the right side
of the module.
Wearing the antistatic wrist strap, install the memory module in the first
available memory slot to the right of the CPU. Ensure that the memory
module is vertically aligned. Push the memory module in until the ratchet
handles engage with the enclosure frame. Push the ratchet handles inward
toward the rear of the cabinet until the memory module is firmly seated
in the backplane. When the memory module is firmly seated, the ratchet
handles will lock the module in place.
Note
The CPU and MS690 memory modules are equipped with ratchet
handles (Figure 3–1) which are shipped in a horizontal position. The
ratchet handles are designed to ensure that the modules are properly
seated in the backplane connectors.
4. Close the H3604 console module and lock the 1/4-turn captive screws.
5. To identify the memory module, place the MS690 option label (supplied
in the option kit) in the proper location on the H3604 panel. Indicate the
revision number and memory option (BA, CA, or DA).
