Chapter 4 Aggregator TAPs

rev. 1

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).

Technical specifications

This section lists the dimensions, power requirements, supported

media, and environmental requirements. For the regulatory

compliance statements, see “FCC compliance statement” on page 24.
