How-To: Init HPE FF5700 FlexFabric Switches

Left alone by some consultants, which charged a lot and did not accomplish to much, I ended up configuring FF5700 felx fabric switches myself. Some of the insights, other posts will follow.

To start with the basic initialization settings, configuring management access and doing initial firmware maintenance. After unpacking the switch and mounting fans and power supplies connect through the serial console – although there is dhcp client running on the switch which probably allows you to gain management access over the network. Remember there is a Gigabit- Ethernet- Port on the backside of the switch, dedicated for management access only. The console port is adjacent. Default serial settings are 9600/n/1/n as with any other HPE switch.

Zuallererst muss man das gute Stück am Management- Port auf einen untagged Switchport verbinden. Mit Strom versorgt springt irgendwann die Status LED von orange auf grün und man kann sich mit den Default Koordinaten über das System her machen.
