F.2 LED Mounting Locations
This section describes the physical LED mounting locations on each component.
- Components equipped with Power, Alarm, and Location LEDs have the LEDs mounted as follows.
- The order of mounted LEDs arranged from left to right is as follows: Power, Alarm, Location.
- The order of mounted LEDs arranged from top to bottom is as follows: Power, Alarm, Location.
- From the standpoint of appearance, components equipped with LAN ports have the Speed LED on the
left and the Link/Act LED on the right of each port.
