14.1 Power Failure

NEC recommends that each user set his/her own password

from Set Password under the Administration section.

The system allows connection for basic telephone service during a power failure.

The power failure operation occurs during a commercial power failure, and is not

affected by blade failure. Power Failure Transfer is provided by connecting to the

GCD-4COTB blade.

The GCD-4COTB Blade provides 2 Power Failure Transfer circuits.

The CN3 and CN5 connectors each provide connection to four analog trunk ports,

which are polarity sensitive (tip to tip, ring to ring). The power failure circuits,

however, are not polarity sensitive. A maximum of 15 GCD-4COTB blades per

system is allowed.

When connecting the RJ-61 cables to the COIU Blade, note the

position of the Power Failure connector.

Do not confuse connector CN3 as the CN2 trunk connector.

Unit Reboot: After applying the changes, click unit reboot

and follow the prompted steps resulting in the reboot of the

NEC's IP6-L Adapter can be reset to factory

defaults by clicking "Factory Default" under the

Administration section of the GUI interface.

If the GUI interface is not available, set DIP

switch 4 to the ON position and boot the unit.

After 30-45 seconds the unit should be

completely booted. Set DIP switch 4 back to the

OFF position.
