Adding UPS Support to an Existing VCX System 127
Requirements Setting up a VCX system to use UPS power and to monitor UPS status
using the
vcx-ups-setup command requires the following configuration
information for each UPS in the VCX system:
■ IP address of the UPS — You must know the pre-configured IP address
assigned to the UPS.
■ SNMP community string — You must know the pre-configured SNMP
write community string assigned to the UPS.
■ Low battery threshold percentage — You must specify the battery
charge level (expressed as a percentage of battery capacity) at which
point the attached server (or servers) should initiate a shutdown.
You must also supply the following information for each VCX server:
■ Whether a server is the master or a slave
■ On each slave server, the IP address of the master VCX server
Adding Single UPS
Device Support
This section describes how to configure a VCX system supported by a
single UPS. Depending on your VCX configuration, this requires one or
two general steps:
■ If your VCX system includes a single VCX server, configure that system
as the master.
■ If your VCX system includes multiple VCX servers, configure one server
as the master and the remaining servers as slaves.
Single UPS System – Configuring the Master VCX Server
To initially enable and configure a VCX server as the master in a single
UPS system:
1 Log in, using the root account, to the VCX server you want to designate
as the master.
2 Enter the following command:
vcx-ups-setup <configuration_parameters>
You must concatenate the following vcx-ups-setup command
configuration parameters (responses are shown in bold):
-- master: Y
Enter Y (you must uppercase) to designate this server as the master.
-- monitormultipleups: N
