Airflow bottom-to-top

[marmat8951]

NetBox version

v4.0.8

Feature type

Data model extension

Proposed functionality

We think it would be interesting to get airflow options going from the bottom to the top to be added, as they are crucial to monitor in order to do not use the u upper or lower with a full-length equipment. It should only be implemented by adding the current existing air-flow options as an implementation. Upper or lower air-reserved U should be reserved by the users themselves and should not be added in the data-model.

Use case

We currently have old Huawei DSLAM type MA5600 that have fan slots over the top for a bottom-to-top air flow.
In more modern equipements we have Huawei MA5800 versions X15 and X17 OLT doing such things.

We have as well modern transmissions equipement that uses a filter slot in the bottom and a fan slot on top of them, such as Huawei OSN 9800 M12 https://support.huawei.com/enterprise/en/optical-transmission/optix-osn-9800-m12-pid-23815286

Database changes

Should only require new entries on air-flow options.

External dependencies

No response

You might as well add 'left to right' and 'right to left' too.
Some of the larger Cisco chassis have fans on the sides that pull/push air from the side of the chassis.
Cisco 4500 chassis for example.

Perfect timing to discover this issue and piggyback.
We recently tried to add some equipment that has rear-to-sides.

Hello,

there's a good chance we'll need top-bottom airflows very soon in $dayjob, so happy to contribute a changeset for this.

thanks
