Spine Board Led Indicators; Table 5: Connector Physical And Logical Link Indications - Mellanox Technologies MSX6512-4R. Hardware Installation Manual

InfiniBand Switch Platform Hardware User Manual
This LED lights up when one or more ports is receiving a symbol error. The LED imme-
diately goes off until the next symbol error is received.
2.1.2.3 UID LED Switch Identifier
The UID LED is a debug feature that will become available to customers in the near
future. For details please contact Mellanox Technologies support.
2.1.2.4 Leaf Board Port Connector LED Assignment
Above the ports are two LEDs one for the upper port
Each port has a single 2 color LED. Table 5 shows the link status according to the LED
condition.

The LED indicator, corresponding to each data port, will light orange when the physical
connection is established (that is, when the unit is powered on and a cable is plugged into
the port with the other end of the connector plugged into a functioning port). When a log-
ical connection is made the LED will change to green. When data is being transferred the
light will blink green.

Spine Board LED Indicators

Each leaf board is connected by links to each spine module. Each spine has the following
LEDs.
• One status LED for the spine health
• One status LED for the spine fan modules
• 36 status LEDs showing the existence of leaf to spine connections
• One Bad Port Led showing symbol errors in the data stream
• One UID LED that can be lit to identify an individual spine
The 36 LEDs on each spine are divided by the number of leafs and the result (N) is the
number of connections from each leaf that are connected to the spine. 6 spines must be
installed and working to ensure that full BW exists between nodes. The maximum num-
ber of connections from each leaf is 3. If the (number of leafs) x (the maximum number

A problem with the physical link
The switch does not provide a visual means to indicate the port speed configuration
(SDR, DDR, QDR, or FDR) and/or the link width (1X or 4X). The speed and link
width configurations can be retrieved using management software.
