Maintenance Port
Through the maintenance port (sometimes called the modem port), you can connect either a single
workstation running an IP-based application or a terminal server that supports multiple workstations.
The workstation must support SLIP. Typically, use of this port includes a modem because the shelf
resides at a remote location. The typical applications are software and firmware download or tasks that
require low-level access.
Other Ports
Other ports exist on the PXM1-UI and PXM-UI-S3. These ports support external clock sources and
external, third-party audio or visual alarm systems. For information on the function of other ports, see
Chapter 6, “Card and Service Configuration”
IP-Based Applications
The maintenance port and Ethernet port support IP-based applications. Through these ports, the
following applications run:
• Telnet supports CLI command execution from any IP-based application window as well as a window
in the Cisco WAN Manager application.
• TFTP lets you download firmware and upload and download configuration information.
• SNMP supports equipment management through the CiscoView application and connection
management through the Cisco WAN Manager application.
MGX 8230 MGX to BPX Feeder
As a BPX feeder, the MGX 8230 concentrates user ATM, Frame Relay, and circuit emulation traffic and
feeds it to a BPX 8000 series switch over an OC-3 or OC-12 feeder trunk. The BPX series switch
performs the switching and routing of the MGX 8230 user-connections through an MGX and BPX
network. Figure 5-1 is a simplified diagram of the MGX 8230 MGX feeder application.

Initial MGX 8230 Bring-Up
This section describes how to start up the MGX 8230 for the first time. It begins with an MGX 8230
PXM that has only boot-mode firmware. The descriptions tell you how to:
1. Establish communication with the MGX 8230.
2. Configure one or more boot-level IP addresses to make the MGX 8230 available to the network.
