Labelling and Asset management is very important.

We use a mix of labelling on racks, server, network switches and network cables each brings different challenges and different solutions

racks are typically labelled with enscribed panels squares screwed/glued into racks
servers have used both printed labels and barcode labels in the past which can then use handheld scanners and integrated with asset management tools.
cable labelling at either end of cables find a4 printer laser sheets are better than handheld printers for this for speed and lastibility of the labels as handheld printers seem to fall off after a while. Have used key fobs etc in the passed but they need to be flexible for cable removal and consume a lot of space.

You can now get intelligent cable management systems that record your labelling and connections but at the end of the day labelling is only as good as the day it was installed and requires constant approach to get teams to get it uptodate and standardised.
