not receiving any traffic.
Blinking. Port is linked and traffic is being
received or transmitted by the interface.
Recommended Action
If the LED remains off after connecting AC
power or DC power from an RPS, check the
following:
1. Make sure there is power at the power
source (AC source and RPS if applicable).
2. Replace the power cord with a known
good one or check the continuity of the
power cord.
3. If the switch still does not power up, the
system may have a fatal error. Contact
Enterasys Networks for technical support.
If the LED remains red for several minutes,
the system may have a fatal error. Contact
Enterasys Networks for technical support.
If the LED remains amber for more than
several minutes, contact Enterasys Networks
