Replacement Procedures
Caution –
Before touching or replacing any component inside the server, disconnect
all external cables. If possible, place the server on a grounded electrostatic-discharge
(ESD) pad and ALWAYS wear a properly grounded, antistatic wrist strap.
Caution –
The auxiliary CPU card is not a hot-swappable component. You must
power down the server before removing the card.
Note –
It is not necessary to remove the system cover when working with the CPU
card. Procedures involving the CPU card can be performed with the server mounted
in a rack. If it is in a rack, pull the server forward from the rack about 3 inches
(76 mm) to provide clearance before opening the CPU card door.
