Installing Memory

This section describes the procedure for installing memory. For memory installation,
see "2.2 Checking the Memory Configuration
Fit the notched section of the memory into the corresponding position of the
1.
connector of the memory slot.
2. Push the memory module evenly into the slot.
Note - Confirm that the latch of the memory slot has returned to its original position.

Installing a CPU Memory Unit

This section describes the procedure for installing a CPU memory unit.
Unless otherwise specified, the figures explained in this section use the SPARC
M10-4S with a FRAME-A CPU memory unit.
Caution - When mounting a CPU memory unit board, check the connectors on both
of the CPU memory unit board and frame beforehand to confirm that no pin is bent
and all the pins are neatly arranged in lines. If there is a bent pin in a connector,
mounting a CPU memory unit board may damage the CPU memory unit or frame.
Also, carefully proceed with the work to prevent any pin from being bent.

Installing the CPU memory unit upper

Note - A part of the procedure varies depending on the CPU memory unit type. To
determine the CPU memory unit type, check the label in
Install the CPU memory unit upper on the CPU memory unit lower. When replacing
the CPU memory unit lower, install the CPU memory unit upper on the new CPU
memory unit lower.
For expansion of a CPU memory unit upper, perform the same procedure. When
removing the CPU memory unit upper, install a filler unit in its place.
1. When installing a filler unit for the CPU memory unit lower connected to PCIe
cables, push the PCIe cables (A and B in
the chassis.
Note - Be careful when removing the filler unit so that it does not catch on any PCIe cable.
Rules," and install memory accordingly.
