What do the LEDs mean on the FLEX-adapters?

The LEDs on the FLEX-Base are as below.

A. Ethernet Uplink

1. 1. Ethernet RJ45 Connector LEDs:

   • Link Status (LEFT - green)

   • Activity Status (RIGHT - amber)

   • The link status LED indicates the connection status as follows:

     • Off: No connection.
     • On: Link is good.

   • The activity status LED indicates network activity as follows:

     • Off: No activity.
     • Flashing: Network activity is present.

2. Ethernet Downlink

1. Downlink Port LEDs:

   • Link/Speed Status (LEFT - green or amber)

   • Activity Status (RIGHT - amber)

   • The link/speed LED indicates the network status and speed as follows:

     • Off: No link.
     • Green: Link is good with a network speed of 100Mbps.
     • Amber: Link is good with a network speed of 10Mbps.

   • The activity status LED indicates network activity as follows:

     • Off: No activity.
     • Flashing: Network activity is present.

The LEDs on the FLEX-adapters: FLEX-C and FLEX-Link are as below. 

A. Ethernet Downlink
            (1) The Ethernet downlink RJ45 port shall have two LEDs to indicate network connection
                  status: Link status (LEFT - green) and activity status (RIGHT - amber).
            (2) The link status LED indicates the following: Off – no connection. On – link good.
            (3) The activity status LED indicates the following: Off – no activity. Flashing – network
                  activity.
B. Long Reach Ethernet
             (1) The long-reach Ethernet RJ45 port shall have two LEDs to indicate connection status:
                  Link/speed status (LEFT - green or amber) and activity status (RIGHT - amber).
             (2) The link/speed LED indicates the following status: Off – no link. Green – link good with
                  a network speed of 100Mbps. Amber – link good with a network speed of 10Mbps.
             (3) The activity status LED indicates the following; Off – no activity. Flashing – network
                  activity.

The LEDs on the FLEX-04 are as below. 

A. Ethernet Downlink
             (1) Each of the four downlink Ethernet RJ45 ports shall have two LEDs to indicate network
                  connection status: 100Mbps speed (RIGHT - green) and 10Mbps speed (LEFT - amber).
              (2) The green LED indicates the following: Off – no connection. On–link good at 100Mbps,
                   Flashing – Network activity.
              (3) The amber LED indicates the following: Off – no connection. On–link good at 10Mbps,
                   Flashing – Network activity.
B. Long Reach Ethernet
              (1) The long-reach Ethernet RJ45 port shall have two LEDs to indicate network connection
                   status: 100Mbps speed (LEFT - green) and 10Mbps speed (RIGHT - amber).
              (2) The green LED indicates the following: Off – no connection. On–link good at 100Mbps.
              (3) The amber LED indicates the following: Off – no connection. On–link good at 10Mbps.
