Dear all,

please:

1. Plan your network infrastructure.
2. Buy the hardware.

Don’t do the opposite! Once again, I was ordered to a company to configure the already bought switches (they didn’t contact me before to plan it correctly). I went to the datacenter and saw the HPE 5700 series switches… without a fan, only a power supply… nice!

If you want to do the initial configuration, you will see only this on the console port:

The amount of normal fans is less than 1.

The amount of normal fans is less than 1.
The amount of normal fans is less than 1.
The amount of normal fans is less than 1.
The amount of normal fans is less than 1.

you can’t configure the switch because if you have no installed fan, the device won’t boot the software-image… I tried anything to come further, but had no success:

HP has so many helpful tools and website-informations for you. Here you have an overview of all network switches, you can easily compare the switches and look for hardware informations. HPE Networking Online Configurator gives you a perfect tool to build an order-ready excel sheet with recommendations (like a minimum of one power supply and one fan for the 5700 series).

Thank you for for your patience :)
