Sample Services Configuration Script — Primary Server (continued)
Do you wish to change any of the System parameters? [N] :
Press the Enter or Return key to accept the default answer (N). If you
want to change any of the values, enter
Y.
----------- Configuring additional parameters for UPS Monitoring -----------
An Uninterruptible Power Supply (UPS) can be used with VCX systems to avoid
disruption due to a power outage. VCX provides a UPS monitoring service
which tracks the UPS's status and performs a safe shutdown when the its
battery is depleted during a long power outage. To use this feature, you
must have a compatible UPS installed and configured in accordance with the
VCX documentation.
Enable UPS monitoring? [N] :
Press the Enter or Return key to accept the default answer (N). You can
deploy a UPS in either a branch office or regional configuration. For the
current VCX software release, 3Com Corporation supports UPS hardware
from American Power Conversion (APC) Corporation. (For a list of
supported APC UPS devices, consult with your 3Com Service
Representative or your 3Com Voice Authorized Reseller.) If you answer Y
to this question, the script prompts you with further questions about your
UPS configuration.
It is possible to use multiple UPS units to power a single server if the
server has redundant power supplies with separate power connections.
Will multiple UPS's power this server? [N] :
Press the Enter or Return key to accept the default answer (N) if you will
use only one UPS to power this server. If you will use more than one
server, enter Y.
A single UPS can power one or more VCX systems. A UPS 'Master'
communicates directly with a UPS, while a 'Slave' communicates with the
Master to get UPS status. Only one 'Master' system should monitor a given
UPS. If this VCX system is the only one connected to the UPS, say 'Y'
here. Note: a VCX system's UPS Monitoring role is independent of any other
role it may have within a VCX deployment.
