      - copper (terminations are required) Cat5e and Cat6
  - - - 19 inches wide
        
        dont overstack units
        
        racks can be mutiple units tall
  - - - Provider (Demarc)
        
        Can be standard or have an extension but that is provider responsibility
      - Primary equipment room or Main Distrubution Frame (MDF)
      - Intermediate Distribution Frame (IDF)
  - - - Keystone jack then pop the wires out then punch them down and cut off extra
        
        Then cable test
- - - - Easy maintance without full removal
    - - Taking air in through front and removing to the rear
        
        When designing servers make sure exhaust is keeping flow correctly
    - - Circuits

  - - - Category Lots of connections (all are different but diminishing over time) they go into lime card
      - Clock Rates
      - DCE/DTE
      - T-1/E-1 - Frame Rate
      - Tons of things in it up to 60 pins
      - RS232 Comm port 9 pins. Older tec to connect network components. Now its used to configure cisco connections like switches or routers.
      - Most are USB to RS232 jumper to configure router or switch
