Chapter 5 The Configuration Utility
PLA-401 Series User’s Guide
39
Firmware is the software which is embedded in the PLA-401 Series. This software
contains processing instructions for how the PLA-401 Series sends and receives
information in a secure way.
Parameter Information Block (PIB) is similar to firmware. It contains the most
basic operating instructions for the PLA-401 Series such as how to power up and
how to load the firmware.
You can check the ZyXEL website for firmware upgrades for your PLA-401 Series.
Note: To upgrade to the latest firmware, use the firmware upgrade tool available from
the ZyXEL website (www.zyxel.com), or from the CD included with your PLA-
401 Series. Make sure you also upgrade the PLA-4xx Series Configuration
Utility if you do so, as older version utilities are not compatible with PLA-401
Seriess using the latest firmware.
Note: Be sure to upload the correct model firmware as uploading the wrong model
firmware may damage your device.
