11.6 Firmware Upgrade Screen
Find firmware at www.zyxel.com in a file that (usually) uses the system model name with a “*.bin”
extension, e.g., “PLA.bin”. The upload process uses HTTP (Hypertext Transfer Protocol) and may take up
to two minutes. After a successful upload, the system will reboot.
Click Maintenance > Firmware Upgrade. Follow the instructions in this screen to upload firmware to your
PLA.
Daylight Savings Daylight saving is a period from late spring to fall when many countries set their clocks
ahead of normal local time by one hour to give more daytime light in the evening.
Select this option if you use Daylight Saving Time.
Start Date Configure the day and time when Daylight Saving Time starts if you selected Daylight
Savings. The o'clock field uses the 24 hour format. Here are a couple of examples:
Daylight Saving Time starts in most parts of the United States on the second Sunday of
March. Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local
time. So in the United States you would select Second, Sunday, March and type 2 in the
o'clock field.
Daylight Saving Time starts in the European Union on the last Sunday of March. All of the
time zones in the European Union start using Daylight Saving Time at the same moment (1
A.M. GMT or UTC). So in the European Union you would select Last, Sunday, March. The time
you type in the o'clock field depends on your time zone. In Germany for instance, you
would type 2 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).
End Date Configure the day and time when Daylight Saving Time ends if you selected Daylight
Savings. The o'clock field uses the 24 hour format. Here are a couple of examples:
Daylight Saving Time ends in the United States on the first Sunday of November. Each time
zone in the United States stops using Daylight Saving Time at 2 A.M. local time. So in the
United States you would select First, Sunday, November and type 2 in the o'clock field.
Daylight Saving Time ends in the European Union on the last Sunday of October. All of the
time zones in the European Union stop using Daylight Saving Time at the same moment (1
A.M. GMT or UTC). So in the European Union you would select Last, Sunday, October. The
time you type in the o'clock field depends on your time zone. In Germany for instance, you
would type 2 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).
