5.3 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 plugable".

CLK1, CLK2:

"hot plugable"

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".

RSC/SPT:

"hot plugable"

The switching function or the distribution of
generated signals is interrupted while the RSC/SPT
is disconnected.

———————————————————————————————————————————–

CPU:

"hot plugable"

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.
