Installing MPUs for the S12516R and S12508R
For the S12516R and S12508R, the ejector levers of the MPUs and the ejector lever pillow blocks on
the MPU slots have pink marks. The MPU installation procedure is the same for the S12516R and
S12508R. The following uses the S12516R as an example.
To install an MPU:
1.
As shown by callout 1 in
, remove the filler panel from the target MPU slot.
Keep the removed filler panel secure for future use.
2.
, orient the MPU with lettering on it upright. Hold the MPU by
the front panel with one hand and support the bottom with the other. Push the MPU steadily into
the slot along the guide rails.
Keep the MPU parallel to the slot to avoid touching other components in the chassis.
3.
As shown by callout 3 in
, pull the ejector levers of the MPU outward when most part
of the MPU is inserted in the slot.
4.
Push the MPU until the brakes on its ejector levers touch the slot edges tightly.
5.
As shown by callout 4 in
, continue to push the MPU by its middle part on the front
panel until you cannot move it.
6.
As shown by callout 5 in
, push the ejector levers inward until they come in close
contact with the front panel.
7.
As shown by callout 6 in
, fasten the captive screws on the MPU.
