• HP recommends mid-range N class and low-end L-class systems and PA-8500-based workstations
to obtain optimal performance when running Java applications. The recommended minimum
system for running Java applications is a PA-RISC 2.0 system or a PA-RISC 1.1 system with a
floating-point coprocessor. For information on setting important system parameters required for

1. During installation you must be logged in as “root.”
2. If using a serial port connection to the UPS, use the SAM utility to disable getty or uugetty at
system startup from monitoring the port where you are connecting the UPS. Optionally, you can
delete or comment the following line (or similar) from the
/etc/inittab
file:
ttp1:234:respawn:/usr/sbin/getty –h tty0p1 9600
3. If you are using an SNMP card, check for SNMP daemons. Execute the command
ps -ef | grep -i snmp
. If the processes snmpd or snmpdm are running, they must be disabled
before you can install Liebert MultiLink.
If you are not using an SNMP hardware card with your UPS, Liebert MultiLink can use its
If you are not using an SNMP hardware card with your UPS, Liebert MultiLink can use its
default port settings of 3029/3027, and there is no need to disable the SNMP daemons.
4. Make sure the Liebert MultiLink distribution file has execute permission (
chmod +x <file>
),
then execute it.

If you do not have enough disk space in the /tmp partition to meet the requirement specified in
A.6.1 - Platform-Specific Requirements, you may specify an alternate location when starting the
installation. For example, to use /home/tmp, start the install with the following command:
./ML_36_003_HP-UX.bin /home/tmp
Serial Port Selection
The preconfigured serial ports are
/dev/tty0p0
and
/dev/tty1p0
. You may select one of these or
enter another as appropriate.

It also creates K300LiebertM and S900LiebertM links in the
/sbin/rc1.d
and
/sbin/rc2.d
directories.
