Flashing Orange
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. 18 spines must be
installed and working to ensure that full BW exists between nodes. The maximum num-
ber 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 Table 6. The LEDs
indicate as follows.

Data activity – flashing speed is proportional to data transfer speed
Physical link up
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.
