-48 VDC Remote Power Manager

Installation and Operations Manual
SNMP/Thresholds
The -48 VDC family of products supports the Simple Network Management Protocol (SNMP). This allows network
management systems to use SNMP requests to retrieve information and control power for the individual outlets.
The unit includes an SNMP v2c agent supporting standard MIB I and MIB II objects. A private enterprise MIB
extension (Sentry3 MIB) is also supported to provide remote power control.
NOTE:
For security SNMP support is disabled by default.
About SNMP Versions
The firmware supports SNMP versions 1, 2, and 3.
SNMP version 3 supports authentication and encryption on a per user basis. Authentication types are None and MD5.
Encryption types are None and DES. If you use authentication, you must use encryption.
Two SNMPv3 users are supported: one user with read-write (RW) access, and one user with read-only (RO) access
Both users have the same configuration parameters, and you can configure each user independently.
SNMPv2 and SNMPv3 can be enabled or disabled independently. You can have SNMPv2 and/or SNMPv3, or none.
SNMP CLI Commands:
All SNMP v3 specific configuration settings use the CLI command SET SNMP V3.
All SNMP v1/v2 specific configuration settings use the CLI command SET SNMP V2.
All SNMP configuration settings common to any SNMP version use the CLI command SET SNMP.
NOTES:
If you use SNMP v1 or SNMP v2, all SET SNMP CLI commands (and the SHOW command) require the “V2” keyword.
SNMP v1/v2 CLI commands are documented immediately below in this section showing the required “V2” keyword. All CLI commands
that follow the SNMP v1/v2 section in this manual assume SNMP v3.
