How to Check How to Check the Z the Z- - SUS Stand
The Power Supply should be producing VS or you can substitute voltage matching VS from an external
source to either pin 1 or 2 P102 on the Z-SUS board.
The Power Supply should be producing M5V or you can substitute Stand-By 5V or any 5V from an
external source to the 5V Fuse on the Z-SUS (FS202). Note: The 5V will be routed back to the Control
Board for power through the P201 to P2 connector.
The Power Supply should be producing 17V or you can substitute voltage matching 17V from an pp y
external source to either pins 1 or 2 on connector P2 on the Control board.
1) Disconnect P811
2) Disconnect P105
Tip: If the DC to DC converter generating 18V is running on the Y-SUS, you can jump any 5V to the Y-SUS M5V Tip: If the DC to DC converter generating 18V is running on the Y-SUS you can jump any 5V to the Y-SUS M5V
input pin, leave P105 connected and there will be no need to jump the 17V or the M5V to the Z-SUS.
