In each case, a check is required as to whether this technology is supported
by the active network components and operating systems in use.
The power supply units of active network components constitute a frequent
source of errors, as these units have to rely on a stable mains voltage. For
this reason, many components can be retrofitted with redundant power
supply units, or are already equipped with them before delivery. This
lowers the failure susceptibility of individual network components without
requiring their duplication. However, this measure does not increase the
operational reliability of the network components as such.
In each case, a careful analysis is required to determine the actual availability
requirements. As part of a detailed planning of the system and network
architecture, a suitable redundancy concept must be developed to fulfil these
requirements. In this context, also refer to S 6.18 Provision of redundant lines.
Additional controls:
- Have network availability requirements been ascertained and documented?
- Are all important network components replicated in a warehouse, or have
delivery contracts been concluded in this context?
- Has the redundancy of components been taken into account during
planning of the network?
