whether there is any traffic present. If a Link LED is unlit, there is
no functioning device connected to that port.
See “How do I connect my failover devices?” on page 55 for details
about what happens when a primary device fails.
Error conditions are shown by the Speed LEDs for approximately 10
seconds, after which the TAP resets itself (goes back to the Search
connection step).
