Zhone Technologies Network Device manual

Zhone Technologies, Inc. IMACS Product Book, Version 4

To manage the IMACS containing the B7R card, a separate SLIP/PPP connection from the DB9 on the interface card is required. The local IMACS cannot route its own SNMP information to an internal B7R card. For example, if a network has eight remote nodes, two SLIP connections are required at the central site - one for the eight remote IMACS and one for the local IMACS.

The Management Channel Concentrator (MCC) card allows management of the local system as well as 128 remote IMACS nodes. The remote systems may either be communicating using B7R on TS 24 (T1) or B4R on TS31 (E1) directly, via a cross-connect or be using FDL (T1) /SA4 (E1) with a DACS version 6.2 or equivalent. In addition, the MCC card has also four ports configurable with for a variable number of nx64 kbit DS0s. These can be used to forward already concentrated IP traffic down to a second MCC card.

Any SNMP manager can receive the SNMP trap and respond by initiating a TELNET session with the originating IMACS for diagnostics and control. Note that the local and remote reporting feature of the IMACS is disabled if the TCP/IP network management feature is active. The IMACS supports sending traps up to three SNMP trap servers, allowing alarms to be sent to multiple network management stations.

However, once the cards are installed and the chassis populated, these identifiers are no longer visible.
