IMC Card

Chapter 2 Description

•Three DS3 (BNC) connectors for channelized DS3 service interfaces.

•Two OC3 connectors (second connector used for SONET 1+1 APS) for ATM trunk.

•RS232/RJ45 Console port for CMDR.

The Integrated Management Controller (IMC) provides centralized out-of-band management connectivity to the MGX 8240 switch. The IMC can manage (detect and reset) all PSM cards in a switch—up to 15. The IMC has the following functions:

•Allows the MGX 8240 to be seen and accessed from the Ethernet as a single entity with a single IP address, instead of as 15 separate PSM cards or switches. The IMC does Network Address Translation, routing IP traffic to each card within the chassis. The NAT supports FTP, Telnet, SNMP, and ICMP traffic.

•Provides timing to all cards; timing comes from two BITS clocks through the IMC.

•Monitors the chassis information regarding fan trays, temperature, alarm relay, and power input and communicates results to the management station.

•Monitors the IMC card; each of the two cards in the chassis monitors the other.

•Sends traps to management station regarding status of IMC card and PSM cards.
