The SNMP agent software is intended to run on an ATCA-F125/F140 blade and should be
preinstalled together with the remaining ATCA-F125/F140 software. If you need to reinstall or
update the SNMP agent software, refer to
Installing an SNMP Agent on page 31 . For details about
how to configure the SNMP agent, refer to Configuring an SNMP Agent on page 33 .
1.4 High Availability
The Artesyn HPI-B implementation described in this manual supports the following two
redundancy options:
 Active/active
 Cold-standby
The active/active option is the default configuration. Both HPI daemons in shelf are active and
run simultaneously. Your application connects to one daemon and if the connection fails it
connects to the second daemon. Note that the current HPI-B implementation does not
replicate any data between the two daemons, this means data consistency is not guaranteed.
Alternatively you may choose to use the cold-standby redundancy option. In this configuration
your application must make sure that only one HPI daemon is active at a time. If the daemon
fails, your application starts up the second, previously inactive daemon and connects to it.
During start-up the HPI daemon scans the current system environment. This way it is ensured
that the daemon reflects the current system configuration.
