Table 8: Status LED on Network Ports in EX3200 and EX4200 Switches (continued)
State and Description LCD Indicator LED
Indicates the speed.
The speed indicators for network ports on the front panel are:
■ One blink per second—10 Mbps
■ Two blinks per second—100 Mbps
■ Three blinks per second—1000 Mbps
The speed indicators for network ports on the SFP uplink
module are:
■ Green—1000 Mbps
■ Unlit—10/100 Mbps
The speed indicators for network ports on the SFP+ uplink
module are:
■ Green—The speed of the transceiver installed in the port
is the same as the speed at which the uplink module port
is configured to operate.
■ Unlit—The speed of the transceiver installed in the port
is not the same as the speed at which the uplink module
port is configured to operate.
The speed of the XFP uplink module ports is always 10 Gbps;
therefore, the LED is always green.
