a. Inspect the connector on the board being installed.
Remove the connector protective cover. Check to see if the plastic is deformed or
damaged, including both the pin holes and the fins. Insure there are no major (out
of the normal) gaps between each pin row.
b. Insure the CPU/Memory board alignment tabs are not bent.
c. Check the CPU/Memory board springfingers for damage.
d. Check the chassis springfingers for damage (SB5 for Sun Fire E6900 and SB4 for
Sun Fire E4900 systems.)
8.3.1.3 Installing the CPU/Memory Board
1. Remove the CPU/Memory board filler board or filler panel.
Caution – You must insert a CPU/Memory board into the system within one
minute of removing the filler board or filler panel or overheating will occur.
2. Make sure that the ejector levers of the CPU/Memory board are in the open
position. They should be 90 degrees straight out from the board (
Caution – Do Not Force any board into a slot; it can cause damage to the board and
system. The board should insert and seat smoothly. If it binds, remove the board and
inspect the card cage slot for any obvious obstructions. Also inspect both the board
and the centerplane for bent pins or other damage.
3. Gently insert the CPU/Memory board into the grooves into the proper slot (see
TABLE 8-2
The top of the board is noted by the thin rail. The bottom of the board has a thicker
rail. The board LEDs should be at the bottom of the handle when the board is
inserted properly into the card cage for the E6900/E4900 systems.
a. Hold the board by the handle with one hand. Place the other hand on the
bottom mounting rail holding the board vertically.
b. Install the board in the chassis by tipping the handle of the board down so that
the bottom rail meets the bottom chassis guide rail.
c. When the bottom board rail is in the chassis guide rail, tip the board back up
and align the top rail into the chassis rail guide.
d. Slide the board into the chassis slowly until the ejector lever handles start to
collapse inward.
