The following figure shows an application that uses a redundant pair of
H1 with Integrated Power cards and Megablocks for short circuit protection for
devices on a long (0.5 km) trunk cable. If a failure occurs, the operator
receives a hardware alert and the segments continue to operate as expected. If
a short occurs when a device is installed or removed from the segment, only
that device is affected; the rest of the segment continues to operate. A power
supply is required if an H1 card is used. It is assumed that the application
design follows the criteria specified in the
DC power considerations for high availability applications that use the H1 with Integrated Power card
topic.
