Management Connections

This switch can be managed over any of the SFP or XFP slots, or over the 
100BASE-T RJ-45 management port. The 100BASE-TX port can be configured in 
an isolated VLAN to provide a dedicated management channel that operates outside 
of the data transport network, making it possible to re-configure or troubleshoot the 
switch over either a local or remote connection to the management port when 
access via the data channel is not possible or deemed insecure.

The figure below illustrates management-port connections to FTTH switches.
