Header Update In order for customers to use their existing daughtercards in a Vanguard 340/342
chassis, they will have to use a different size daughtercard header. The product code
that supports the Vanguard 340/342 is 1152-10006.
Installation Figure 1 shows the different style daughtercard header pins. The newer header pins
for the Vanguard 340 and 342 are shorter than the header pins in an older unit. The
shorter pins connect to the motherboard.

Note
Most older style cards can be used in the Vanguard 340 and 342 units. The
minimum revision that can be used for the FXS/FXO card is B. Do not force any
older cards into the newer units, they should fit
easily.
