18.1 I/O Port Power for the XIG 12 Port Rev A/B Models
Jumpers J2A, J2B and J2C provide the ability to power on or off the I/O section of a port in
groups of four. Removing the jumpers will remove power from the DC-DC converter and all
components in the isolated section of the product.
This mode can be used in cases where power is in short supply and the group of ports is unused.

The factory default is to have all three jumpers installed to enable all three banks of ports.
Note about Fusing: Each bank is protected by a resettable fuse from damage due to circuit failure
or overload. To reset the fuse, the power should be removed for a minimum of one minute.
Never adjust these jumpers while the power is on!
