Juniper EX2200 Complete Hardware Guide

The LEDs labeled Status LED in Figure 5 on page 12 and Figure 6 on page 12 indicate the
status of one of the four port parameters—speed, duplex mode, administrative status,
and Power over Ethernet (PoE) status. Use the mode button below the POE LED on the
far right side of the front panel to toggle the Status LED to show the different port
parameters. You can tell which port parameter is indicated by the Status LED by seeing
which port status mode LED (SPD, DX, EN, and POE) is lit. (See Figure 6 on page 12).
Table 6 on page 13 describes the Status LED.

State and DescriptionPort Parameters
Indicates the speed. The speed indicators for network ports are:
•
One blink per second—10 Mbps
•
Two blinks per second—100 Mbps
•
Three blinks per second—1000 Mbps
The speed indicators for uplink ports are:
•
On steadily—1000 Mbps
•
Off—10/100 Mbps
Speed
Indicates the duplex mode. The status indicators are:
•
On steadily—Port is set to full-duplex mode.
•
Off—Port is set to half-duplex mode.
Duplex mode
Indicates the administrative status. The status indicators are:
•
On steadily—Port is administratively enabled.
•
Off—Port is administratively disabled.
Administrative status
Indicates the PoE status. The status indicators for network ports are:
•
On steadily—PoE is available on the port, a device that draws power from the port
is connected to the port, and the device is drawing power from the port.
•
Blinking—PoE is available on the port, but no poweris drawn from the port because
of one of the following:
•
No device that draws power from the port is connected to the port.
•
A device that draws powerfrom the port is connected to the port, but the device
is not drawing any power from the port.
•
Off—PoE is not available on the port.
PoE is not available on uplink ports; therefore, the LED for those ports is always unlit.
PoE status
You can tell which port parameter is indicated by the Status LED on network ports and
uplink ports by issuing the operational mode command show chassis led.
