Which Firmware Version to use for Upgrades --------------------------------------------------------- To upgrade a print server's firmware, you will need to determine what the current firmware version is. This is important because firmware upgrades must be kept within the same series (V1.41 to V1.43, not V1.41 to V2.45). For example, a 5435e with a firmware version of 1.41 can only be upgraded with firmware versions in the 1.xx series (such as 1.43). If the wrong firmware is applied, the print server could be damaged requiring the unit to be returned to I-O for repair. There are four methods that can be used to determine what is the current firmware version: 1. Print the print server's configuration report -- the "software" version is found on the third line. 2a. Using the current I-O Configuration Utility -- After you have double clicked on the desired device from the List of Devices, you will be presented with the Print Server Information screen. The firmware version along with other general information about the device will be presented. 2b. Using the older (and now discontinued) PrintControl utility -- After you have double clicked on the desired print server from the List of Print Servers, you will be presented with the Print Server Information screen. On the right side in the Object Information panel, you will find the "Firmware Revision" number. 3. Check the color of the network link and activity LEDs on the side of the print server. If both are green, then use version 1.xx. If one is green and the other is yellow, use version 2.xx. If both are yellow, use version 3.xx 4. The serial number of the print server. See the table below. The following table lists firmware version series for each LAN Print Server model and hints on selecting the right version using the color of the LEDs and serial number: Model Version How to Determine Which Version to Select -------------------------------------------------------------------------------- 5409 1.xx will always have firmware version 1.xx 5430 1.xx Will always have firmware version 1.xx 5430b 1.xx Check LEDs on the side, both will be green or 2.xx Check LEDs on the side, Activity LED will be green, Link LED will be yellow - Serial number 8140457 and newer or 3.xx Check LEDs on side, both will be yellow Serial number 8131838 and newer or 4.xx Check LEDs on the side, Activity LED will be yellow, Link LED will be green - Serial number 8158594 and newer 5430e 2.xx Check LEDs on the side, Activity LED will be green, Link LED will be yellow - Serial number 8140457 and newer or 3.xx Check LEDs on side, both will be yellow Serial number 8131068 and newer or 4.xx Check LEDs on the side, Activity LED will be yellow, Link LED will be green - Serial number 8158594 and newer 5431b 1.xx Check LEDs on the side, both will be green or 3.xx Check LEDs on side, both will be yellow Serial number 8141150 and newer or 4.xx Check LEDs on the side, Activity LED will be yellow, Link LED will be green - Serial number 8156767 and newer 5435 1.xx will always have firmware version 1.xx 5435dp 1.xx Check LEDs on the side, both will be green or 2.xx Check LEDs on the side, Activity LED will be green, Link LED will be yellow - Serial number 8131242 and newer or 4.xx Check LEDs on the side, Activity LED will be yellow, Link LED will be green - Serial number 8155903 and newer 5435e 1.xx Check LEDs on the side, both will be green or 2.xx Check LEDs on the side, Activity LED will be green, Link LED will be yellow - Serial number 8131222 and newer or 4.xx Check LEDs on the side, Activity LED will be yellow, Link LED will be green - Serial number 8155903 and newer 5450 1.xx Will always have firmware version 1.xx 5450e 3.xx Check LEDs on the side, both will be yellow Serial number 8138489 and newer or 4.xx Check LEDs on the side, Activity LED will be yellow, Link LED will be green - Serial number 8158809 and newer 5735dp 2.xx Check LEDs on the side, Activity LED will be green, Link LED will be yellow or 4.xx Check LEDs on the side, Activity LED will be yellow, Link LED will be green - Serial number 8155903 and newer 5735E 4.xx check leds on the side. activity led will be yellow. link led will be green. 5735km 4.xx check leds on the side. activity led will be yellow. link led will be green 5755dp 2.xx Check LEDs on the side, Activity LED will be green, Link LED will be yellow or 4.xx Check LEDs on the side, Activity LED will be yellow, Link LED will be green - Serial number 8155903 and newer 5755e 2.xx Check LEDs on the side, Activity LED will be green, Link LED will be yellow or 4.xx Check LEDs on the side, Activity LED will be yellow, Link LED will be green - Serial number 8155903 and newer 5755km 4.xx check leds on the side. activity led will be yellow. link led will be green 5794 IP 3.xx check leds on the side. both will be yellow.
