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.
