Introduction to
Krone block
replacement
This procedure describes how to remove and replace a Krone block in
Horizon
macro outdoor cabinet.
Two Krone blocks for external alarms and communications interfaces are
mounted on the top panel of the cabinet. Since they are an identical fit, the
following procedure describes how to replace either of them.
The Krone blocks can be replaced without interruption to normal operation of
the equipment, provided the associated customer alarms and communications
signal losses are accounted for.
