(Link or Activity) On or flashing Green The SFP port has established a valid 100/1000 Mbps link.
Flashing indicates the port is transmitting and receiving user
packets.
Off A link is not established with a remote port.
Table 7. Four-port 10 Gbps SFP+ module status LEDs
LED Condition Status
Link or Act LED
(Link or Activity) On or flashing Green The SFP+ port has established a valid 10 Gbps link. Flashing
indicates the port is transmitting and receiving user packets.
Off A link is not established with a remote port.
Note: The two left ports (ports <stack id>/2/1 and <stack id>/2/2) on the
four-port 10 Gbps SFP+ module do not pass regular Ethernet traffic by
default. If you want all four ports on the four-port 10 Gbps SFP+ module to
pass regular traffic, the global CLI command,
stack disable , must be
configured on the device to disable stacking. For more information, see the
FastIron Configuration Guide .
16/10 Gbps Ethernet CX4 stacking ports
The 4002-Y2B and 4002-Y4B devices include two 16/10 Gbps Ethernet CX4 ports
on the rear panel. The device can perform data transmission directly through
copper links of up to 3 meters.
These CX4 ports are configured by default as 16 Gbps stacking ports which can
connect to other 4002-Y2B and 4002-Y4B devices in a stack of up to eight members.
Stacking simplifies deployment, management, and allows for data traffic to
traverse over these high-speed stack links. The CX4 ports can also be configured to
operate as 10 Gbps Ethernet ports by either disabling stacking on the device (
stack
disable ) or configuring other ports to be the default stack ports ( default-ports ),
and then setting the speed-duplex settings to 10 Gbps ( speed-duplex ). See the
FastIron Configuration Guide for additional details on stacking and configuration.
The Up Link and Down Link LEDs on the front panel indicate operational status.
If the
Up Link or Down Link LED is on, the port is connected. If the Up Link or
Down Link LED is off, no connection exists, or the link is down.
