Theory of operation
The Wave Server chassis has been designed with a single power supply. If the power supply
becomes nonoperational, the entire chassis will cease to operate, and all voice and data calls will
be terminated.
The power supply can become nonoperational due to an internal component failure, if the power
supply switch is turned to the Off position or if external power is removed either by unplugging
the power cord or turning off external power.
Activities allowed when power is on
The following activities are allowed when the power is on:
•
Plugging in additional cables to the digital station card, analog station card, analog DID
trunk module, analog trunk module, analog universal module, and T1/E1 modules for
ports that have already been configured
Caution:
Do not install or replace cards or modules while the Wave Server is powered on.
For information about replacing a nonoperational power supply, refer to Chapter 6, “Field
Replaceable Units (Wave IP 2500 only).”
Activities allowed only when power is off
The following activities are allowed only when the power is off:
•
Installation or replacement of cards and modules
•
Installation of an EXU
•
Upgrade or replacement of system card components, such as the battery, VAM, hard
drives, and MRM
•
Installation or replacement of the power supply tray
•
Installation or replacement of a hard drive
