Cisco MGX 8230 Edge Concentrator Installation and Configuration
Release 1.1.31, Part Number 78-11215-03 Rev. B0, May 2001
Chapter 5 Configuring the MGX 8230 Shelf
MGX 8230 MGX to BPX Feeder
3. Download MGX 8230 PXM firmware.
4. Configure a new, MGX 8230-level Ethernet IP address for the MGX 8230 PXM as needed or other
SLIP or IP addresses.
5. Specify a name for the MGX 8230.
6. Specify the time on the MGX 8230.
7. Optionally configure a time zone for the Western Hemisphere, or configure a time zone relative to
Greenwich Mean Time if the MGX 8230 resides outside the Western Hemisphere.
8. Download firmware to the service modules.
If the MGX 8230 PXM has no runtime (or “on-line”) firmware Image, begin with the boot-mode
description in the “Bringing Up an MGX 8230 PXM With No Run-time Firmware” section on page 5-4.
If the MGX 8230 PXM has a run-time firmware image, go to the section “Bringing Up an MGX 8230
PXM With No Run-time Firmware.”
Bringing Up an MGX 8230 PXM With No Run-time Firmware
The section describes the tasks for loading runtime firmware onto a MGX 8230 PXM that has only a
boot loader.
Step 1 Establish communication with the MGX 8230 by doing one of the following:
• Connect a cable between your terminal or PC and the PXM-UI or PXM-UI-S3 control port.
• If you are using an ASCII terminal connected to the control port, the prompt for the next command
is already present upon power-up. (If the display is skewed, make sure the terminal speed and
PXM-UI or PXM-UI-S3 port speeds are the same.)
• If you are using a utility such as Hyper Terminal on a PC, the firmware may reside on either a floppy
or the hard drive.
Step 2 Execute the command bootChange to configure boot-level IP parameters.
If the MGX 8230 has a redundant MGX 8230 PXM, execute bootChange on each MGX 8230 PXM to
configure unique, boot-level IP addresses. (During the subsequent MGX 8230-level configuration, you
must configure another Ethernet IP address that applies to both MGX 8230 PXMs.) The following are
the only parameters that are meaningful at this point, so press Return other parameters:
• Mandatory “host name” is a name for the workstation. For the MGX 8230, enter the letter c.
• Ethernet IP address and subnet mask for the MGX 8230 PXM LAN port are mandatory (see “inet
on Ethernet” in the following example). Follow the IP address with a colon and a net mask. The
netmask is eight hexadecimal numbers with no embedded periods. Do not type spaces on either side
of the colon.
• If the workstation from which you download firmware is on a subnet other than the subnet of the
MGX 8230 PXM, enter a gateway IP address (“gateway inet”).
Note the three editing functions near the top of the following example. Of these, typing a period to the
clear the current field is the most commonly used.
