12.7.1 Important Hints for hot-pluggable IMS Modules
The following points should be strictly observed when replacing IMS modules during operation. Not all IMS
modules are fully hot-pluggable. Of course, it is not possible to replace a power supply unit of a non-redundant
system without first having installed a second power source in operational mode.
The following applies to the individual IMS slots:
I/O, ESI and MRI Slots
=
"hot swappable".
CLK1, CLK2
=
"hot swappable" but a rescan of the reference clocks (Rescan Refclocks)
must be executed in the web interface menu "System" after the exchange
or installation of a clock module.
CPU
=
The central management unit is not "hot swappable", i.e. the system must
be disconnected from mains before replacement.
RSC/SPT
=
The RSC switching card is not "hot swappable", i.e. the system must
be disconnected from the mains before replacement.
