(flashing amber, blinking green, or solid green). If the RX LED is off

of the link.
b. Verify that the fiber strands between the applicable port on the
2H28-08R and fiber optic device on the other end of the fiber optic
link segment are properly crossed over.
c. Make sure that the fiber connection meets dB loss specifications
outlined in Section 2.2.
d. To manage the connected port, see Section 5.11.
If a link has not been established, refer to Chapter 4, Troubleshooting,
before contacting the Cabletron Systems Global Call Center. Refer to
Section 1.6 if the problem has not been resolved.
NOTE
The port RX LED flashes green and amber during bootup.
