Connect USB Power
STEP 1 Turn on the IPS device.

Figure 2 - 9: USB Connection
Note: If you connect two IPS USB cables to the ZPHA device, the ZPHA will
continue to function if one of the devices loses power. The ZPHA bypasses the IPS
only if all power from the IPS devices interrupts. If two IPS devices are connected,
both would have to lose power to cause the ZPHA to bypass.
