Chapter 5. UPDATING FIRMWARE
5.1 Updating Firmware via the Internet
TO ENSURE OPTIMAL PERFORMANCE, IT IS IMPORTANT TO OPERATE THE CRS-500
WITH ITS LATEST AVAILABLE FIRMWARE.
The CRS-500 1:N Redundancy System is factory-shipped with its latest version of operating
firmware. If a firmware update is needed, it can be acquired by download from the Comtech EF
Data Web site ( www.comtechefdata.com ); it may also be obtained from Comtech EF Data
Customer Support during normal business hours via e-mail or on CD by standard mail delivery.
The CRS-500 Firmware Update process is as follows:
• Download the new firmware update for upgrading the CRS-500 to a user-provided PC
intended for Monitor and Control (M&C) of the CRS-500 1:1 Redundancy System.
• Connect the CRS-500 to an available serial port on the user PC.
• Extract the firmware update from the transferred archive file, and then execute the
upgrade process via File Transfer Protocol (FTP) from the user PC to the CRS-500 as
specified in this chapter. The upgrade can be performed without opening any of the
CRS-500 component chassis (e.g., CSU, DSU, etc.).
5.2 Getting Started: Preparing for the Firmware Download
1. First, identify the CRS-500 assigned Management IP Address, and obtain the firmware
number, revision letter, and version number.
User-supplied items needed:
• A Microsoft Windows-based PC, equipped with available serial and Ethernet ports; a
compatible Web browser (e.g., Internet Explorer); and a terminal emulator program (e.g.,
Tera Term or HyperTerminal).
• A 9-pin serial cable to connect a user PC serial port to the CRS-500 (for use of the serial-
based remote product management interface).
