Older Vanguard Daughtercards do not fit into the Vanguard 342. You can only use 
the newer daughtercards which are identified by a dimple as shown in Figure 2-4. If 
the dimple is not present, do not attempt to use the Daughtercard in the Vanguard 
342.  and V.34 Daughtercards are obsolete.

Also, when installing a Vanguard Daughtercard into a Vanguard 342, you must use 
the shorter two-sided header. The taller header is used with other Vanguard units.

If you attempt to force an older Vanguard Daughtercard into a Vanguard 342, the 
equipment will be damaged.

If you have an older Vanguard Daughtercard and would like to use it in a Vanguard 
342, contact your VanguardMS representative about having the card reworked.
