[AusNOG] Switch installation in data centre racks - front facing, or rear facing?

[Paul Wilkins]

Just so. If you care about configuration control and change management,
you'll be using structured cabling with access from the front of the rack.
You really don't need to be fiddling around in the back of a rack,
wondering about which port goes where.

Kind regards

Paul Wilkins
