https://community.extremenetworks.com/t5/extremeswitching-eos/c2g124-24-firmware-unable-to-boot/m-p/80951#M2171 Hello guys,<BR /> I have a problem with C2G124-24 switch. It looks like it cant boot because all leds are on while CPU led is blinking green. I tried to connect to the switch via putty but nothing appeared (yes, I pressed enter/space). So I tried to download new firmware, and upload it directly on card storage of the switch, but switch is still not responding. Can you please help me with this switch? Thank you! <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span> <BR /> <BR /> <P class="fancybox-image"><span class="lia-inline-image-display-wrapper" image-alt="947b0a042e7344bfba96e5be3bdd4466_ebda6ca1-78bb-4ca9-8e9a-4ef5e74a95c4.jpg"><img src="https://community.extremenetworks.com/t5/image/serverpage/image-id/3436i328B248FAA32FFBD/image-size/large?v=v2&amp;px=999" role="button" title="947b0a042e7344bfba96e5be3bdd4466_ebda6ca1-78bb-4ca9-8e9a-4ef5e74a95c4.jpg" alt="947b0a042e7344bfba96e5be3bdd4466_ebda6ca1-78bb-4ca9-8e9a-4ef5e74a95c4.jpg" /></span></P> Thu, 14 Feb 2019 05:33:46 GMT DFH 2019-02-14T05:33:46Z https://community.extremenetworks.com/t5/extremeswitching-eos/c2g124-24-firmware-unable-to-boot/m-p/80951#M2171 Hello guys,<BR /> I have a problem with C2G124-24 switch.
