  Fiber optic connector      CN1       6-pin DIN (Optical         CN3
  - ST (Phy A)                         Bypass Switch)

  Fiber optic connector      CN2
  - ST (Phy B)

  Note: Type A (Phy A) or Type B (Phy B) connectors are usually
  distinguished by a marking on the male ST (i.e. if using a blue ring to
  route transmit signals from the 4811, do the same for all other
  devices). CN1 is keyed for an A type connector, and CN2 is keyed for a
  B type connector.
