Groups 2 through 6 have 25-
Ω
fixed termination resistors due to space
limitations, and have one bypass capacitor for every four termination resistors.
The 25-
Ω
termination is optimized for estimated 25-
Ω
loaded-line impedance.
The termination cards can remain installed on the backplane board or be
removed during storage and transit. Both termination cards can be stored in
the same slot in the tray (see Figure 2–14) or stored separately. If stored
together, the resistor/capacitor sides must face each other.
