In the first software release, two users are configurable in the FRM220 NMC. Currently, either user will have full control over
all configuration and monitoring functions of the management system. In some future release, the management will be divided
between different access levels and users will be assigned a level appropriate to their level of authority in the management
scheme. For now, set at least one user and password to protect Telnet and Web access by unauthorized personnel.
3.2.8 Upgrading the NMC
The design of the Network Management Controller is built around a 32 bit embedded processor that uses an
open source Linux kernel and customized software on top. Line cards are designed using 8 bit 8051
microprocessors that handle all configuration of the line card through software and provide the communication via
RS-485 bus from the card to the Network Management Controller (NMC). The NMC and any line cards, including
any remotely connected (over fiber) in-band managed converters, are all capable of online software upgrade.
The purpose of this section is to outline the procedures and pitfalls in upgrading the NMC of the FRM220.
3.2.8.1 Preconditions
The original version 1.0 hardware NMC was released with SNMP code version 1.0x for the FRM220. Software
upgrade is performed by the user by interacting with the NMC via the serial console port on an ASCII terminal
(optionally via Telnet). The software transfer mechanism is the TCP/IP protocol TFTP (Trivial File Transfer
Protocol). The end user or network engineer can perform an upgrade easily from one personal computer or from a
Laptop Computer.
3.2.8.2 Items required
a. The FRM220 unit with NMC installed, configured and network connected. Version 1.0X to be upgraded to version 1.0Y.
b. A Windows® based PC with a network connection and with at least one free COM port and terminal emulation software
(such as HyperTerminal) or Telnet.
c. Serial console cable (DB9M to DB9F) [not required if performing by Telnet]
d. Ethernet UTP cables
e. FRM220-NMP latest version Linux kernel or ROMFS file system
f. CTC Union TFTP server for Windows® (or other TFTP server)
3.2.8.3 Equipment Setup
The upgrade procedure should not have any effect on the traffic passing through an online FRM220 unit. It is
not required that the unit be taken offline for maintenance.
Two connections are required between the PC that will do the upgrade and the FRM220 that will be upgraded.
First, a console connection, with terminal emulation program such as HyperTerminal with settings of 115.2K baud,
8 bits, no parity, 1 stop bit, and no flow control. The second connection is an Ethernet connection, either through a
network or with a direct connection via UTP cable.
Check the Ethernet settings of the FRM220 through the console mode (refer to Chapter 3 Provisioning). Either
change the settings to match the network settings of your PC or set the PC's settings to match the FRM220's
network settings. In the following example, we are on a 192.168.1.0 network with a subnet mask of 255.255.255.0
and a default gateway of 192.168.1.254. Our PC is set with an IP address of 192.168.1.100 and our FRM220 has an IP
address of 192.168.1.1. (factory default settings)
