Emerson Liebert PSA Line-Interactive UPS 500-1500VA User Manual

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:

• Oracle Solaris version 9, 10 or 11 on an UltraSPARC processor
• Appropriate patches applied to operating system. For patches required to run Java 1.6, see:

• 100 MB of free disk space (during installation, the /tmp partition must have 150 MB free)
• 512 MB of RAM
• Common Desktop Environment or Oracle OpenWindows (X Window System)
• A mouse or other pointing device
• TCP/IP network protocol

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 pmadm utility to disable ttymon from 

monitoring the port. To disable ttymon, you must perform the following command:

pmadm -l

This command lists the PMTAG and SVCTAG for each port. You will substitute the values of 

these tags in the following command:

pmadm -d -p {PMTAG} -s {SVCTAG}

3. If you are using an SNMP card, check for SNMP daemons. Execute the command

ps -ef | grep -i snmp

. If the processes snmpdx 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, then 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.3.1 - 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_40_001_Solaris.bin /home/tmp

The preconfigured serial ports are 

/dev/term/a

 and 

/dev/term/b

. You may select one of these or 

enter another as appropriate.

The Liebert MultiLink installation program places the script 

LiebertM

 in the 

/etc/init.d

 directory. 

It also creates K30LiebertM and S90LiebertM links in the 

/etc/rc1.d

 and 

/etc/rc2.d

 directories.

If running the Common Desktop Environment (CDE), all users meant to receive pop-up messages 

must allow access to their desktop. This can be accomplished by adding the following command to a 

common logon script (e.g., /etc/profile)—see the CDE documentation or xhost man page for more 

information about the desktop security mechanism:

/usr/openwin/bin/xhost +`hostname`

Note: The characters surrounding hostname are the grave accent (

`

) that is usually found on the 

same keyboard key as the tilde (

~

).
