The 10BASE-T Ethernet rear card’s 10BASE-T interface is configured as a DTE
(Data Terminal Equipment), just like a 10BASE-T network interface card in a PC.
Therefore, it expects to connect to a 10BASE-T hub using a straight-through RJ-45
cable. Use Figure E-5 to construct a cable to connect the rear card to a 10BASE-T
hub.
