The processing blades take approximately 40 seconds to boot from power on.
At the end of the boot-up, each processing blade loads the latest settings (stored at shut-down).
PSU Status LEDs
Each power supply has two status LEDs that can be used to check the health of the PSU:
LED 1 (power) - lights in green when the power is ok.
LED 2 (fault) - lights in amber if there is a fault or warning.
The table below describes all possible states.
PSU LED Condition(s) Meaning Recommended Actions
1 - Off
2 - Off No power. No AC (or DC) input. Check the AC mains supply and IEC
connection.
(For a DC supply, check the disconnect
device/power distribution).
1 - Green
(blinking)
2 - Off Standby ON; Main output OFF;
AC (or DC) present. AC (or DC) input
detected; PSU is starting. Wait for PSU to start.
1 - Green
(solid)
2 - Off Standby ON; Main output ON.
No errors detected. PSU is active; no errors. Normal operation; no action required.
2 - Amber
(solid) Main output overcurrent,
undervoltage or overvoltage.
Fan fault or overtemperature.
Standby overcurrent or
undervoltage. Internal fault. Check the PSU Health pages (in
HOME's Advanced parameters).
2 - Amber
(blinking) Power supply warning event
triggered. Internal warning.
Installing a Frame with DC Power Supplies
To use the DC power supplies option, there are several conditions that must be observed:
The use of DC power supplies is only permitted if your system is installed in an area with restricted access (to skilled
persons only).
The device with its PSU and the complete DC mains power distribution system must be placed entirely within a single
building.
The ground (PE) terminal of the .edge frame must be connected to the ground (PE) of the DC mains power distribution
system.
It is mandatory to install some means of cable strain relief for the wires that feed each PSU.
For example, by installing a clamp on a 19-inch panel mounted above the .edge frame.
Or, if this is not possible, by fixing the wires to the PSU handles using some cable ties (as shown below).
The cable strain relief will need to be removed and replaced if you need to exchange a PSU.
