Key Description
A Green LED if on, confirms power is on and unit is not in Standby mode

C Rocker switch to turn PSU on and off
D Ethernet port. Two Ethernet ports are available. Port 1 is the left-hand
connector when the nShield nShield 5c is viewed from the back
E RJ45 port for a serial console cable
If you connect only one Ethernet cable to the nShield nShield 5c,
Entrust recommends that you connect it to Ethernet port 1. This is the

left-hand Ethernet connector on the rear of the nShield nShield 5c
(shaded in the image).
If the green LED is on, the PSU is operational and receiving power, and is not in Standby
mode. If a power cable is not fitted correctly, or a rocker switch is not turned on, an
audible warning is given and the orange warning LED on the front panel is turned on.
