The device then binds the recovery IP, <code>192.168.1.30</code>, to the first interface it sees as &ldquo;up&rdquo;.</p> <p>Here is the trap. An installed SFP+ module will probably report &ldquo;up&rdquo; before any of the RJ45 LAN ports do. The recovery IP binds to the SFP+ interface, and you sit there wondering why you cannot ping <code>192.168.1.30</code> from a LAN port. Remove the SFP+ module, power the device back into recovery mode, and the LAN ports work.</p>
