3.1 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:
PWR:
"hot swappable"
If you operate your system with only one
power supply, a second power supply must
be installed before removing/replacing it
to keep your system functioning.
I/O, ESI and MRI Slots:
"hot swappable".
CLK1, CLK2:
"hot swappable"
Afer the exchange or the installation of a
clock module a rescan of the reference clocks
(Rescan Refclocks) must be executed in the web
interface menu "System".
CPU:
"hot swappable"
The NTP service and access to the web interface
are interrupted while the CPU is disconnected.
Also the management and monitoring functions are
no longer available.
RSC/SPT:
"hot swappable"
The switching function or the distribution of
generated signals is interrupted while the RSC/SPT
is disconnected.
