Node Removal 1. Allow 2-3 minutes for the node to halt, then verify the Node Status LED is flashing green and the Node UID LED is blue, indicating the node is halted. CAUTION: The system does not fail if the node is properly halted before removal, but data loss may occur if the replacement procedure is not followed correctly. NOTE: The Node Fault LED may be amber, depending on the nature of the node failure. Figure 22 Verify Node Status LEDs NOTE: Nodes 1 and 3 are rotated in relation to nodes 0 and 2. See Figure 19 (page 17). 2. Ensure that all cables on the failed node are marked to facilitate reconnecting later. 3. Remove cables from the failed node. 4. Pull the node rod to remove the node from the enclosure. 5. When the node is halfway out of the enclosure, use both hands to slide the node out completely. 6. Set the node on the ESD safe mat next to the replacement node for servicing. 7. Push in the failed node's rod to ready it for packaging and provide differentiation from the replacement node. Node Replacement 1. Move both SFPs from the onboard FC ports on the failed node to the onboard FC ports on the replacement node: a. Lift the retaining clip and carefully slide the SFP out of the slot. b. Carefully slide the SFP into the FC port on the replacement node until it is fully seated; close the wire handle to secure it in place. 2. If a PCIe adapter is installed in the failed node, move the SFPs from the PCIe adapter on the failed node to the PCIe adapter on the replacement node: a. Lift the retaining clip and carefully slide the SFP out of the slot. b. Carefully slide the replacement SFP into the adapter on the replacement node until it is fully seated; close the wire handle to secure it in place. 3. On the replacement node, ensure that the gray node rod is in the extracted position, pulled out of the component. Controller Node (Node) Replacement Procedure 21

Node Removal
1.
Allow 2-3 minutes for the node to halt, then verify the Node Status LED is flashing green and
the Node UID LED is blue, indicating the node is halted.
CAUTION:
The system does not fail if the node is properly halted before removal, but data
loss may occur if the replacement procedure is not followed correctly.
NOTE:
The Node Fault LED may be amber, depending on the nature of the node failure.
Figure 22 Verify Node Status LEDs
NOTE:
Nodes 1 and 3 are rotated in relation to nodes 0 and 2. See
Figure 19 (page 17)
.
2.
Ensure that all cables on the failed node are marked to facilitate reconnecting later.
3.
Remove cables from the failed node.
4.
Pull the node rod to remove the node from the enclosure.
5.
When the node is halfway out of the enclosure, use both hands to slide the node out completely.
6.
Set the node on the ESD safe mat next to the replacement node for servicing.
7.
Push in the failed node’s rod to ready it for packaging and provide differentiation from the
replacement node.
Node Replacement
1.
Move both SFPs from the onboard FC ports on the failed node to the onboard FC ports on
the replacement node:
a.
Lift the retaining clip and carefully slide the SFP out of the slot.
b.
Carefully slide the SFP into the FC port on the replacement node until it is fully seated;
close the wire handle to secure it in place.
2.
If a PCIe adapter is installed in the failed node, move the SFPs from the PCIe adapter on the
failed node to the PCIe adapter on the replacement node:
a.
Lift the retaining clip and carefully slide the SFP out of the slot.
b.
Carefully slide the replacement SFP into the adapter on the replacement node until it is
fully seated; close the wire handle to secure it in place.
3.
On the replacement node, ensure that the gray node rod is in the extracted position, pulled
out of the component.
