About this task

Use these instructions when you need to replace the Ethernet edge board in a SAN Volume Controller 2145-SV1 node. The Ethernet edge board contains 10 Gbps electrical Ethernet ports.

Procedure

  1. Before you power off the node, verify that hosts will not lose access to data in volumes. Follow the procedure that is described in MAP 5350: Powering off a node.
  2. Remove and label the Ethernet cables that are attached to Ethernet ports 1-3 ( 8 ,  9 , and  10 ), as shown in Figure 1.

    •  1  Power supply 1
    •  2  Power supply 2
    •  3  Video port
    •  4  Serial port (not used) 
    •  5  Rear USB port 1
    •  6  Rear USB port 2
    •  7  Unused Ethernet port
    •  8  10 Gbps Ethernet port 1
    •  9  10 Gbps Ethernet port 2
    •  10  10 Gbps Ethernet port 3
    •  11  Technician port (Ethernet)

Removing the Ethernet edge board

  1. Disconnect each power supply unit in the node from its power outlet so that the node is powered off.
  2. Confirm that all of the LEDs on the rear of the enclosure are off.
  3. Slide the node out on its slide rails to the fully extended position.
  4. Remove the top back cover, as described in Removing the top covers: 2145-SV1.
  5. Remove PCI express rise assembly 1 without disconnecting any of the fabric cables that are attached to it.
  6. Locate the Ethernet edge board ( 1 ), as shown in Figure 2.

    •  1  Ethernet edge board
    •  2  Screw
    •  3  Location of the port hole
  7. Remove the screw that attaches the Ethernet edge board to the chassis ( 2  in Figure 2).
  8. Push the Ethernet edge board out of the port hole at the back of the node in the direction ( 3 ) that is shown in Figure 2.

Replacing the Ethernet edge board

  1. Insert the new Ethernet edge board through the port hole ( 3 ) at the back of the node, as shown in Figure 3.

    •  1  Ethernet edge board
    •  2  Screw
    •  3  Location of the port hole
  2. Push the Ethernet edge board into the edge connector until it clicks. The face of the Ethernet edge board must be level with the back of the node.
  3. Replace the screw (shown in Figure 4) to secure the Ethernet edge board to the chassis.

    Figure 2 shows where the Ethernet edge board is attached to the chassis ( 2 ).

  4. Replace PCI express riser assembly 1, as described in Replacing a PCI express riser-card assembly: 2145-SV1.
  5. Replace the top back cover, as described in Replacing the top covers: 2145-SV1.
  6. Slide the node back into the rack, as described in Replacing a node in a rack: 2145-SV1.
  7. Reconnect the Ethernet cables to the appropriate ports, as noted in step 2.
  8. Reconnect each power supply unit cable. The node turns on when the power is restored.
