1. Power off the server as described in Section 4.2.1, “Powering Off the Server” on
page 4-2.
2. If the server is in a rack, slide it far enough from the rack so that you can remove
the main cover. If you cannot safely view and access the component, remove the
server from the rack.
3. Remove the main cover as described in Section 4.2.2, “Removing the Main Cover”
on page 4-3.
Caution – There is a power status LED (CR1) on the GRASP board that indicates
whether 3.3V standby power is reaching the GRASP board. The GRASP board is not
hot-swappable and should never be removed while this LED is lit.
4. Squeeze the plastic standoff that protrudes through the GRASP board to press the
standoff’s locking tabs. See
FIGURE 4-34.
If you have difficulty pressing the locking tabs with your fingers, you can use a pair
of long-nosed pliers.
