Power On Robot
This guide is about reliable power on-robot.
For port layout and wiring, see:
Goal
You are done when the device:
- does not brown out during robot enable
- stays reachable while streams are running
Power Inputs
HVS - Raze supports:
- Passive PoE over Ethernet (pins 4/5 = V+, pins 7/8 = GND)
- USB-C power (USB-C port on the Ethernet side)
- Direct DC-in
All inputs feed the same internal bus.
Behavior (as designed):
- reverse polarity and ESD protection per port
- no backfeed between inputs
- highest-voltage input takes priority
Voltage Range
- Rated max input: 36V
- Absolute max input: 42V
Power Draw
Typical:
- Startup: ~10W
- Idle: ~7W
- Heavy load: ~15W
Worst case max: ~25W.
At 5V, 25W is 5A. If you power at 5V (including 5V over passive PoE), size wiring for high current.
Fuse Guidance
A dedicated fused feed is recommended.
A simple rule of thumb many teams use:
- 5A fuse per camera on that line
DC-In Polarity
- GND toward the outside of the device
- Positive toward the inside of the device
Verify
- Boot the device.
- Confirm Ethernet link.
- Open the Web UI.
- Confirm telemetry:
