Device description

2.2 PLB Basic module

Step 2: Update

The PLB indicates that the update is in progress through flashing of the "MT", "RN" and "ER"

LEDs. This display mode starts as soon as the check of the firmware files has been

completed successfully. The PLB applies the files as new operating software and restarts

several times. The update can take up to 5 minutes.

Once the update has been completed, the PLB stops flashing and resumes its normal

function. If necessary, the modem firmware may also be updated when the PLB is first

booted after the update (see "PLB Modem Module (Page 24)").

If the update was not successful, the PLB will usually resume its normal function, but it will

now indicate that maintenance is required through its "MT" LED (stays on). Please contact

Technical Support in this case.

We recommend resetting the PLB to factory settings after the update (see "Reset button

(Page 13)" or "Restart (Page 87)").

NOTICE

A firmware update can take up to five minutes.

When updating the Power Line Booster, the power supply must not be switched off. An

interruption of the power supply may irreversibly destroy the PLB.

Note

Mixed operation with different firmware versions

A basic functionality of the system is also given in mixed operation with different firmware

versions. However, there may be a restriction in the status and diagnostics data. We

recommend you avoid mixed operation as much as possible in productive systems and that

you upgrade the masters first in the case of a system update.
