Status indicators (LEDs)
IN :Green indicates that the external mains supply is present and is
within the normal range.
See Mechanical drawings – VM600Mk2 versions on page 7 and
Mechanical drawings – VM600 versions on page 8.
+5V :Yellow indicates that the +5 VDC supply is being generated and is
within the normal range
+12V :Yellow indicates that the +12 VDC supply is being generated and is
within the normal range
−12V :Yellow indicates that the −12 VDC supply is being generated and is
within the normal range
Connectors
Rear : Two high-current DIN 41612 type H15 connectors.
Sharing of power supply voltages and signals via the VM600Mk2/
VM600 rack backplane (ABE04x).

The table below shows the maximum permissible duration of an interruption (cut) to the external AC or DC
mains supply used as the input voltage to an RPS6U rack power supply.
The maximum duration values depend on the maximum combination load for the RPS6U rack power supply,
the number of RPS6U rack power supplies installed in the rack and the number of modules (cards) installed in
the VM600Mk2/ VM600 rack (the actual load). If an interruption lasts longer than the maximum permissible
duration, then the VM600Mk2/ VM600 modules (cards) installed in the rack may reset.
