134 CHAPTER 8: MANAGING UNINTERRUPTIBLE POWER SUPPLIES
The IP address of the second UPS is 10.230.63.4.
The community string the second UPS will use to communicate with
the master VCX server is private.
The low battery threshold charge is 33%.
After the initial master VCX server configuration, you can change a
parameter value by reentering the vcx-ups-setup command. In the
following example, the low battery threshold charge is changed to 50%:
vcx-ups-setup --master Y --monitormultipleups Y
--upsipaddr 10.230.63.3 --community private
--upsipaddr1 10.230.63.4 --community1 private --bcharge 50
Note that you must include all the vcx-ups-setup command parameters
even if you are only changing a single value.
Dual UPS System – Configuring a Slave VCX Server
To enable and configure a VCX server as a slave in a multiple UPS system:
1Log in, using the root account, to the VCX server you want to designate
as a slave.
2Enter 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: N
Enter N (you must uppercase) to indicate that this server is not the
master.
-- monitormultipleups: Y
Enter Y (you must uppercase) to indicate there are multiple UPS
devices servicing the VCX system.
-- upsserver <IP Address of the master>
Enter the IP address (assigned to eth0) of the VCX server acting as the
master UPS monitor. Use dotted decimal notation but do not enter
leading zeros. For example, enter 10.230.63.3, not 010.230.063.003.
3Repeat steps 1 and 2 for all the other VCX servers in your system that you
want to function as slaves.
