A.1 SNMP Upgrade Procedure
The purpose of this section is to outline the procedures and pitfalls in upgrading
the SNMP of the FRM301.
A.1.1 Preconditions
The FRM301 must be using hardware version 2.0 SNMP card. The Control Card
in the rack must be using version 2.17 CPU firmware version (as of this writing). If an
SNMP option is being installed for the first time, you will also be installing a Control
Card. Now would be the best time to be sure the Control Card has the latest
firmware. The Control Card's CPU firmware upgrade is support by chip replacement
only.
The original version 2.0 hardware SNMP was released with SNMP code version
3.42 for the FRM301. The SNMP is upgraded by using TFTP (Trivial File Transfer
Protocol). The SNMP agent provides the ability to upload the new code, re-flash the
flash memory and reboot with the new SNMP operational code.
A.1.2 Items required
a. The FRM301 unit with SNMP option installed and network connection. Version 3.4X to
be upgraded to version 4.06. (as of December 2006)
b. A Windows® based PC with a network connection and with at least one free Com port,
telnet and terminal emulation software (such as HyperTerminal).
c. Serial console cable (DB9M to DB9F)
d. Ethernet UTP cables
e. SNMP ver. 4.06 binary image file (or newer)
f. CTC Union TFTP server for Windows® (or other TFTP server)
A.2 Equipment Setup
The upgrade procedure could possibly have effect on the traffic passing through
an online FRM301 unit. It is recommended that the unit be taken offline for
maintenance. Obviously, changing of Control Card firmware requires removing the
card with power off. If you are going to upgrade a unit's SNMP while the rack is
online and transmitting traffic, choose a time of day when the few seconds of traffic
interruption will have minimal effect (such as the middle of the night).
Two connections are required between the PC that will do the upgrade and the
FRM301 that will be upgraded. First, a console connection, with terminal emulation
program such as HyperTerminal with settings of 38.4K 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 and crossover UTP cable.
Check the Ethernet settings of the FRM301 through the console mode. Either
change the settings to match the network settings of your PC or set the PC's settings
to match the FRM301's network settings. In the following example, we are on a
172.24.0.0 network with a subnet mask of 255.255.0.0 and a default gateway of
172.24.190.254. Our PC is set with an IP address of 172.24.1.126 and our FRM301 has
an IP address of 172.24.1.4.
