Removing and Replacing a Cell Board The cell boards are located in the right side of the chassis. The cell power must be turned off to replace this FRU. See "Powering down Hardware Components and Powering on the Server" (page 103). Cell boards are shipped with all four processors installed. Should the old cell board to be replaced have fewer processors than the new cell board, you must remove the processors from the new cell board to match what the customer has installed on the old cell board. The DIMMs from the old cell board must be transferred to the new cell board. The high-level steps to remove and replace a cell board are: 1. Prepare an ESD safe work surface large enough to accommodate two cell boards. Use a grounded mat and an anti-static wrist strap, such as those included in the ESD Field Service Kit (HP P/N A3024-80004). 2. Place the new cell board on the work surface. 3. Remove the cell board from the server and place it on the work surface. See "Removing the Cell Board" (page 118). 4. Transfer the DIMMs from the old cell board to the new cell board. "Removing and Replacing DIMMs". 5. Remove any additional processors from the new cell board and return the processors with the old cell board. See "Removing and Replacing a Central Processing Unit" (page 139). 6. Install the new cell board in the server. See "Replacing a Cell Board" (page 120).

Removing and Replacing a Cell Board
The cell boards are located in the right side of the chassis. The cell power must be turned off to
replace this FRU. See
“Powering down Hardware Components and Powering on the Server”
(page 103)
.
Cell boards are shipped with all four processors installed. Should the old cell board to be replaced
have fewer processors than the new cell board, you must remove the processors from the new
cell board to match what the customer has installed on the old cell board. The DIMMs from the
old cell board must be transferred to the new cell board.
The high-level steps to remove and replace a cell board are:
1.
Prepare an ESD safe work surface large enough to accommodate two cell boards. Use a
grounded mat and an anti-static wrist strap, such as those included in the ESD Field Service
Kit (HP P/N A3024-80004).
2.
Place the new cell board on the work surface.
3.
Remove the cell board from the server and place it on the work surface. See
“Removing the
Cell Board” (page 118)
.
4.
Transfer the DIMMs from the old cell board to the new cell board.

5.
Remove any additional processors from the new cell board and return the processors with
the old cell board. See

Install the new cell board in the server. See
