If there is a DFE-2616i, DFE-2616ix, DFE-2624i, or DFE-2624ix mas-
ter hub in the stack, then ports can be manually disabled and enabled via
the on-board console interface or via an SNMP-based network manage-
ment program such as D-Link's D-View Network Management
Program. You can choose to partition a port even when there is nothing
wrong with it, for example, to prevent a certain device from accessing
the network.
SNMP Indicator
(Master models only.)
This indicator comes on when the SNMP agent of a DFE-2600 series mas-
ter hub is active. In a stack with both a Primary and a Backup Master, the
SNMP LED of the Primary master will be lit and will flash to indicate
SNMP activity. The SNMP LED of the Backup Master will remain off at
all times.
Port Speed Indicators
There is also a port speed indicator for each of the twisted-pair ports on the
hub. A port's speed indicator should light green when a 100BASE-TX de-
vice is connected to the port, and remain dark if the port is unconnected or
if a 10BASE-T device is connected.
Console Port Indicator (CON)
(Master models only.)
