Vanguard 7300 Platform Version 2
Vanguard 7300 Cards
Description The Vanguard 7300’s midplane slots hold special-purpose printed circuit cards
and rear transition modules accessible from both the front and the rear of the
rack-mounted chassis. Card-swapping time is minimized, port cabling is organized,
and low-level software customizing is eliminated.
Depending on its purpose, a CompactPCI card can be:
• A single card with or without connectors that inserts into a front chassis slot
• A single card with one or more half-sized PMCs mounted on it that inserts
into a front chassis slot
• A two-part card that inserts into a front chassis slot and requires a rear
transition module inserted into its matching rear chassis slot
Figure 1-12 shows a two-part Serial card plugged into the front and rear of the
Vanguard 7300 midplane. The rear transition module has eight ports for cabling from
the rear of the chassis. Fasteners on every card or module lock it securely in its
chassis slot and indicate that the card or module is seated properly.
