the other end of the connector plugged into a functioning port). When a logical connection is
made the LED will change to green. When data is being transferred the light will blink green.
The switch does not provide a visual means to indicate the port speed configuration
(SDR, DDR, QDR, FDR, or EDR) and/or the link width (1X or 4X). The speed and
link width configurations can be retrieved using management software.

3.1.4 Spine Module LED Indicators

Each leaf module is connected by links to each spine module. Each spine has the following
LEDs.
• One status LED for the spine health
• Two status LED for the spine fan modules, one per module
• 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. All spines must be installed and work-
ing to ensure that full BW exists between nodes. The maximum number of connections from
each leaf is 1. If the (number of leafs) x (the maximum number of connections per leaf) is less
than 36 then some of the leaf to spine connection LEDs may be OFF.
The status LEDs for the spine and their descriptions are shown in
follows.
