Module Indicators (SLOT)
The module indicator indicates a good link to a module installed in the re-
spective slot. For the DFE-260S switching module, the indicator will come
on when the module is installed. For the DFE-260FX and DFE-260TX
modules, the slot link indicator should light whenever the module is in-
stalled and there is a valid link.
Note: DFE-916x/DFE-916 can be stacked with DFE-2600 series products
and can be managed through a DFE-2616i/DFE-2616ix or DFE-
2624i/DFE-2624ix master hub.
Port State Indicators
There is one port state indicator for each of the twisted-pair ports on the
hub. Each port’s LED status indicator reports the port’s link and activity
status, and shows whether or not the port has been partitioned.
The following describes each indicator and the meaning of each condition:
♦ Link (green)
The indicator of a port lights green when the port is connected to a
powered Ethernet or Fast Ethernet station. If the station to which the
hub is connected is powered off, or if there is a problem with the link,
the LED will remain off.
♦ Receive (blinking green)
When information is received on a port, its indicator will blink off
briefly. Upon reception, the data will be transmitted to all other con-
nected ports.
