Emerson Liebert PSA Line-Interactive UPS 500-1500VA ユーザーズマニュアル

In addition to the general requirements listed in 3.0 - What is Required to Use Liebert 

MultiLink?, prospective Liebert MultiLink users must also have these minimal requirements:

• HP-UX 11 or 11i
• Appropriate patches applied to operating system. For patches required to run Java 1.4.2, see:

• Common Desktop Environment (X Window System)
• TCP/IP network protocol
• 100 MB of free disk space on the partition where Liebert MultiLink will be installed (during 

installation, the /tmp directory must have 200 MB free)

• A mouse or other pointing device
• 512 MB of RAM
• A minimum of 90 threads per process. This is the kernel parameter 

max_thread_proc

, which can 

be viewed or modified using SAM.

• 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 

correct execution of Java programs, go to 

Comply with the following requirements, then return to 5.1 - Before Installing Liebert MultiLink.
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 

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.

Alternate to /tmp during installation
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

The preconfigured serial ports are 

/dev/tty0p0

 and 

/dev/tty1p0

. You may select one of these or 

enter another as appropriate.

The Liebert MultiLink installation program places the script 

LiebertM

 in the 

/sbin/init.d

 directory. 

It also creates K300LiebertM and S900LiebertM links in the 

/sbin/rc1.d

 and 

/sbin/rc2.d

 

directories.
