Each piece of hardware added to the LIC gets a label: PDUs, PCs and even the mice.
It may seem a little silly to label mice but just wait until you point and click with the wrong one.
My labels are made from a roll of sticky paper letter labels, scissors and a permanent marker (£5).
The labels I bought from the local stationery store were 90mm across. I cut each label into six strips 15mm across. I tried to write on them with a ballpoint pen but it was too faint, so I swapped to a permanent marker. I tried felt tip pen labels a couple of years ago and the ink faded.
I stuck labels onto all hardware. IBM PC base units, KVM (Keyboard, Mouse and Video monitor) sets, network switches, network cables, PDUs (Power Distribution Units), power cables, KVM switches and KVM cables all have sticky paper stuck on them.
|LIC topography: labels|
When I build a rack of computers it is difficult for me to tell which cable plug connects which computer socket to what switch socket. This is because of the slope of my forehead. I help my neanderthal brain figure out what goes where by:
LIC topology: xcl01 interfaces
- using color coded network cables
- labelling each network cable
- writing down what cable goes in which network interface on the ethernet switch (there is not enough room to stick a label by each socket)
I'm actually doing a disservice to neandertals. Apparently their brains were bigger than ours.
Professional. Professional labels are made from flexible nylon tape printed with a top-of-the-range Dymo printer (£150).
Every piece of hardware shown in the layout diagrams gets a label.
