Chapter 9 Product Installation and Hot-Swap Actions
— Configure the product. 
10. When installation is complete and the system is operating as intended, consider if you will want to install 
a replacement Hard Disk Drive (HDD) in the future. If you do, now is an ideal time to perform a backup 
of the System Configuration, which is a necessary step before the HDD can be replaced. For information 
on how to back up the System Configuration, read the instructions in 
Note: The installer or developer must ensure that the product configuration, and any related 
application that is running, provides an implementation that complies with the services offered 
by the local Public Switched Telephone Network (PSTN) operator. In case of doubt, network 
specifications must be consulted.

Power Supply Related Actions
There are many different actions that may be required with regard to the Power Supply Modules and their 
connections. These can be found in the sub-sections below, or referenced from them, as follows: 
Product Installation, Power Wiring for DC Products 
This consists of two essential actions, and one optional action. 
— First connect the Safety Ground Studs as described in 
— Carry out initial wiring of a DC Power Supply Module as described in 
— If the dual redundant option is required, order and install a second DC Power Supply Module. 
Installation of the second module is described below. 
Product Installation, Power Wiring for AC Products 
This consists of one essential actions, and one optional action. 
— Connection of the AC-input Power Supply Cage is described in 
— If the dual redundant option is required, order and install a second AC Power Supply Module. 
Installation of the second module is described below. 
Note: There is no need to connect the Safety Ground Studs on AC powered products, as the Safety 
Ground is provided in the mains cords. 
Second Power Supply Module Installation in DC Products 
This operation is basically the same, whether it is carried out at the time of initial installation of the basic 
product, or if it is decided to add a second DC Power Supply Module at a later date. The benefits of using 
a dual-redundant power supply configuration are described in 
Removal of the filler module is basically the same as removing a DC Power Supply Module as described in 
, which also covers the insertion of the DC Power Supply Module, including the use of the 
'latches'. Take this opportunity to check that the Safety Ground Stud connection is in good order, as 
. Wiring of the second module follows the description in 
Second Power Supply Module Installation in AC Products 
This operation is basically the same, whether it is carried out at the time of initial installation of the basic 
product, or if it is decided to add a second AC Power Supply Module at a later date. The benefits of using 
a dual-redundant power supply configuration are described in 
Removal of the filler module is basically the same as removing an AC Power Supply Module as described 
in 
, which also covers the insertion of the AC Power Supply Module, including the use of the 
'latches'. Connection for the second module simply requires both mains cords to be used on the AC-input 
Power Supply Cage, as described in 
Replacement of Power Supply Module in DC Products 
The general actions required, such as (un)latching, removal and insertion of modules, are described in 
Transferring of the connections from the 'removed' module, to the 'replacement' module, are described 
in 
If replacing a failed module, it is possible that the relevant fuse may need replacement. It should be 
possible to determine if this is necessary from the LED indication on the new module.
