On an EX switch, if you install a transceiver in an SFP uplink module, a corresponding network port from the last four built-in ports is disabled.
If the uplink module is operating in the gigabit mode, the LED is lit. If the uplink module is operating in the 1-gigabit mode, the LED is unlit. You can view the colors of the three LEDs remotely through the CLI by issuing the operational mode command show chassis lcd.
The four figures in this topic show the On steadily—The port and the link are active, but there is no link activity. Off—The port is not active. Table 11 on page 24 describes the Status LED. The speed indicators for network ports on the front panel are: The power supply in EX switches is not redundant.
The PoE power budget for a PoE switch model is determined by the capacity of its power supply. For EX switches, the capacity of the power supply provided with a PoE model is sufficient to supply each PoE-capable port with up to Switches upgraded to Junos OS Release This topic applies only to the J-Web Application package.

Failure to do so https: The rubber feet stabilize the chassis. Align the bottom hole in both the mounting brackets with a hole in each rack rail, making sure the chassis is level.
See Figure 26 on page Before mounting the switch on four posts in a rack: Align the bottom hole in both the front-mounting brackets with a hole in each rack rail, making sure the chassis is level. See Figure 29 on page Mounting an EX Switch in a Recessed Position in a Rack or Cabinet You can mount an EX switch in a rack or cabinet such that the switch is recessed inside the rack from the rack front by 2 inches.
You can use the 2-in. When mounted in a vertical position, an EX switch must be oriented with the front panel of the chassis pointing down in order to ensure proper airflow and meet safety requirements in the event of a fire.
