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
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. 9 spines must be
installed and working to ensure that full BW exists between nodes. The maximum num-
ber of connections from each leaf is 2. 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 Table 5. The LEDs
indicate as follows.
