4.2 Replacing
Blades/RTMs
This section describes how to remove and insert a blade/RTM from/into the compactPCI™
chassis. The blades/RTMs are designed with ejector/injector latches on either side (refer to
the figure below)
to secure the blades to the chassis' cage slots.

4.2.1 Removing
Blades/RTMs
The cPCI blades are designed for hot-swappable capabilities (i.e., they can be inserted and
removed from a slot while the device is under power). However, when the device is a
standalone device engineered in the network with an N+1 redundancy (i.e., other devices
in the network are available to take the load in the event of a blade failure), before
replacing the blades, the chassis must be powered down and
gracefully locked
(i.e., no
new calls are allowed and current calls are terminated after a user-defined interval). The
exception to this is for cleaning or replacing the fan filters, which can be performed while
the system is fully functioning.
The following procedure describes how to remove a blade/RTM from the compactPCI™
chassis.
