DECagent 90 Installation and Configuration

This document, "DECagent 90 Installation and Configuration," serves as a guide for installing and configuring the DECagent 90 network module.

The DECagent 90 is an SNMP (Simple Network Management Protocol) proxy agent designed for Digital's WorkGroup family of products. It provides SNMP proxy support for various DECbridge, DECserver, and DECrepeater modules, automatically discovering most devices within its community (with exceptions requiring manual addition). Management of the DECagent 90 and its managed devices is primarily achieved using SNMP and HUBwatch software.

Key features of the DECagent 90 include:

• Hot-swap capability
• Support for Serial Line Internet Protocol (SLIP) and Trivial File Transfer Protocol (TFTP) for firmware upgrades
• Direct SNMP management and storage of MIB settings in battery-backed RAM
• Out-of-band management options and error-logging
• Capability to manage up to 16 hub communities and 64 network modules
• Deployment as a standalone unit or installed within a DEChub 90 or DEChub 900 MultiSwitch.

The manual provides detailed information across several sections:

• Installation: Instructions for setting up the DECagent 90 as a standalone unit, and for installing it into a DEChub 90, highlighting its hot-swap feature.
