HP 3PAR StoreServ 7450 Storage Service Guide

NOTE: Do not order a replacement node until the ASP has verified the failure, including a
procedure to reset the node.
CAUTION: Alloy gray-colored latches on components like the node means that the component
is warm-swappable. HP recommends that the node be shutdown (with the power remaining on)
before removing this component. Contact your ASP for node diagnosis and shutdown.
CAUTION: To prevent overheating, node replacement requires a maximum service time of 30
minutes.
NOTE: Be sure to wear your electrostatic discharge wrist strap to avoid damaging any circuitry.
Preparation
When the replacement part has been received, complete the following steps before contacting
your ASP for assistance with preparation for replacement:
1. Unpack the replacement node and place it on an ESD safe mat.
2. Remove the node cover:
a. Loosen the two thumbscrews that secure the node cover to the node.
b. Lift the node cover and remove.
3. If a PCIe adapter exists in the failed node:
a. Unpack the replacement PCIe adapter and place it on a ESD safe mat.
b. Remove the PCIe adapter riser card from the replacement node by grasping the blue
touch point on the riser card and pulling the riser card up and away from the node.
c. Insert the replacement PCIe adapter onto the riser card.
d. Replace the PCIe adapter assembly by aligning the recesses on the adapter plate with
the pins on the node chassis. This should align the riser card with the slot on the node.
Snap the PCIe adapter assembly into the node.
4. Replace the node cover:
a. While aligning the node rod with the cutout in the front, and the guide pins with the
cutouts in the side, lower the node cover into place.
b. Tighten the two thumbscrews to secure the node cover to the node.
5. Pull the gray node rod to the extracted position, out of the component.
