Product Description 1-3

Product

Description

The Network Management Card (NMC) has the ability to manage all of

the devices in the Total Control chassis under the direction of any

computer running the console software. This computer is referred to as

the management station (MS).

Two protocols are involved in the implementation of these management

functions:

■Simple Network Management Protocol (SNMP)

■Allows the NMC to communicate with the MS.

■The NMC acts as a proxy agent to the chassis Network Application

Cards (NACs) not running SNMP software directly.

■Management Bus Protocol (MBP)

■Allows the NMC to communicate with and provide configuration

management for the installed devices.

■Supports automatic configuration, status queries, software

upgrades, and event management via the NMC.

Product

Compatibility

Two versions of the 486 NMC NAC are available.

■The 4meg NMC NAC — Support for all non-HiPer applications.

■The 16meg NMC NAC — Support for all standard applications as well

as HiPer Arc and HiPer DSP.

For information on upgrading an existing 4meg NMC, see Appendix B.
