This service action requires you to remove the cover and:
|
v Turn the node off.
|
v Disconnect the power cables.
|
v Disconnect the data cables.

To remove the SAN Volume Controller 2145-CG8 10 Gbps Ethernet riser-card assembly, perform the
|
| following steps:
| 1. Read the safety information to which "Preparing to remove and replace parts" on page 26 refers.
| 2. Perform the procedure to remove the top cover, performing the optional steps to turn off the node
and remove the node from the rack, if it is easier to work on the node that way, as described in
|
| "Removing the top cover" on page 77.
| As you label and remove all cables after turning off the node in the "Removing the top cover" on
page 77 procedure, be sure to remove the serial cable from the UPS that attaches to the serial port on
|
the back of the node before you attempt to remove the fiber optic cable (and the Ethernet small
|
| form-factor pluggable (SFP) transceiver) from Ethernet port 1 in the 10 Gbps Ethernet riser-card
assembly.
|
Remove the two fiber optic cables from the 10 Gbps Ethernet riser-card assembly by pressing their
|
| release tabs and pulling each cable out. Be careful to exert pressure only on the connectors and do not
pull on the fiber optic cables.
|
3. Remove both Ethernet SFP transceivers, as described in "Removing and replacing an Ethernet SFP
|
| transceiver" on page 189 before removing the Ethernet riser-card assembly.
| 4. Remove the two M3 screws that attach the Ethernet riser-card assembly to the back rail.
The 10 Gbps Ethernet riser-card assembly attaches to the back rail with two screws, as shown in the
|
partial view of the rail with the 10 Gbps Ethernet riser-card assembly attached in Figure 189 on page
|
| 193.
