No external network ports are provided on the MA5620E. Can the MA5620E be upgraded through other interfaces in the TFTP mode?
On the MA5620E, 24 or 16 FE ports can be configured. The first FE port is the outband management interface by default and the IP address is x.x.x.x. If the version of the MA5620E needs to be upgraded through TFTP at the local end, connect the PC to the first port and load software and upgrade the MA5620E.
