Figure 1: Switch Front Panel and Locking Mechanism
1.1 InfiniBand Connectors
InfiniBand connectivity has 16 QSFP connectors through the front panel. The remaining 16 inter-
faces are through the AirMax Midplane Connector out the back of the switch. Figure 1 shows the
front 16 ports.
Each of the InfiniBand ports has two LEDs located next to the connector. The green LED, when lit,
indicates that a valid physical connection to the other system (switch or HCA port) exists. The yel
-
low LED when lit, indicates that the Subnet Manager is running and a valid data link exists. The
yellow LED illuminates when the InfiniBand network is discovered over the physical link. A valid
data activity link without data transfer is designated by a constant yellow LED indication. A valid
data activity link with data transfer is designated by a blinking yellow LED indication. If the LEDs
are not active, either the physical link or the logical link (or both) connections have not been estab

lished.
