f.Ensure that the twisted pair connection meets the dB loss and cable specifications outlined in the Cabling Guide. Refer to “Related Documents” in About This Guide for information on obtaining this document.

If a link is not established and it is connected to a PD (Powered Device), check the PoE Port Status to ensure that there is 48 Vdc power at the 4G4285‐49 or 4G4205‐72 RJ45 port. Refer to “Verifying PoE Port Status” on page 3‐19. If there is still a problem, contact Enterasys Networks. Refer to “Getting Help” on page xviii for details.

4.Repeat steps 1 through 3 above, until all connections have been made.

Verifying PoE Port Status

If a PD is connected to the 4G4285‐49 or 4G4205‐72 RJ45 port, ensure that there is power at the RJ45 port as follows:

1.Press on the GROUP SELECT switch for more than one second. The 4G4285‐49/ 4G4205‐72 will enter the PoE status mode, which will indicate a set of power status conditions relating to the PoE Port Status.
