Click the button to search for the Firmware filename.
Note
: SM24TBT2DPA FW v6.54.3104 removed the Force Cool Restart checkbox from this page.
Always On PoE
: Check this button, then during the switch warm restart, it will continue providing PoE
power to the PDs.
Note 1:
It will take 75 - 80 seconds to have PoE++ power on the ports to power PDs
again if the switch makes a cold restart. The "Always on PoE" feature has no effect on this time.
Note 2:
The “Ultra-fast PoE” feature improves PoE startup time; it provides PoE output to attached PDs
within five seconds after a cold start.
Upload
: Click to start the software upload process.
Note
: This page facilitates an update of the firmware controlling the switch. Uploading software will
update the managed switch to the selected software image. After the software image is uploaded, a page
announces that the firmware update is initiated. After about a minute, the firmware is updated and the
switch restarts.
