Removing the expansion unit for a PS704 blade server
To replace an expansion unit in a PS704 blade server, you must first remove the expansion unit.
1.
Read the Safety topic and the “Installation guidelines” on page 229.
2. Shut down the operating system, turn off the blade server, and remove the blade server from the
BladeCenter unit. See “Removing the blade server from a BladeCenter unit” on page 231.
3. Carefully lay the blade server on a flat, static-protective surface, with the cover side up.
4. Open and remove the blade server cover. See “Removing the blade server cover” on page 233.
Note: If you are servicing the base unit of a PS704 blade server, you must first remove the expansion
unit. For more information, see “Removing the expansion unit for a PS704 blade server.”
5. Use your thumb to back out the expansion blade retention thumb screw (

) by rotating the screw
counterclockwise until the connection between the expansion unit and the base unit is loose and the
expansion unit is fully separated from the base unit.
6. Pivot the expansion unit (

in Figure 23 on page 238) up on the cover pins of the base unit (
