11. Attach the metal bracket to the bulkhead with the retaining screw that you removed in step
6.
12. Close the server chassis and slide it back into the rack.
13. Reinstall any cable management components that you removed in step 4.
14. Reconnect the cables that you disconnected in step 3.
15. You are now ready to cable the card , following the cabling instructions for your model of
cluster platform and using the following sequence:
a.
InfiniBand cables, which must be connected according to the port address specifications
for your cluster, as defined in the cluster cabling tables.
b. Communications cables, such as CAT-V Ethernet cables
c. The server's power cord.
d. Begin the node power-up procedures specified for your operating environment. This
information is located in the software documentation.
When you power up the node and connect a link cable to the system interconnect, the HCA-400
LEDs display the link status, as described in
Table 8-1 .
Table 8-1 HCA-400 Status LEDs
Status Description LED Indicator
The green LED (physical link) displays the following status:
• Illuminated: A physical link is present.
• Off: No physical link detected.
• Flashing: There is a problem with the physical link. Green
The amber LED (logical link) displays the following status:
• Illuminated: A logical link is present
• Off: No logical link detected.
• Flashing: There is a problem with the logical link. Amber
After installing the HCA your first task is usually to determine that the its link is correctly cabled
and functioning. Consult the interconnect diagnostics chapter to run the appropriate tests that
will enable you to verify the operation of the card by its LED status array and by test results. The
InfiniBand fabric management software provides a graphical view of the cluster fabric, which
should show that the new HCA is present and functioning correctly. See the Voltaire InfiniBand
Fabric Management and Diagnostic Guide.
Next, boot the operating system and run any diagnostics required to confirm the operation of
the interconnect in the cluster, as specified in the operating environment documentation.
8.3 Topspin/Mellanox PCI-X HCA
The Topspin/Mellanox PCI–X HCA supports InfiniBand protocols including IPoIB, SDP, SRP,
UDAPL and MPI. The Topspin/Mellanox PCI–X HCA is a single data rate (SDR) card with two
4X InfiniBand 10 Gb/s ports and 128 MB local memory.
Figure 8-3 shows a Topspin/Mellanox
PCI–X HCA.
