4.8.2 VPD Installation Considerations
Each I/O card ships with a special VPD (vital product data) PROM (Programmable
•The VPD PROM sockets are next to their respective I/O cards. That is, the left (or top) socket is matched with the left I/O card, while the right (or bottom) socket is matched with the right I/O card. Arrows have been placed on both sockets pointing to their respective I/O cards.
•There is only one correct way to insert the VPD PROM in each socket. This can be done by aligning the notch on the chip with the notch on the socket. However, inserting the chip backwards will not damage it; the port simply will not be able to register properly with the 8285 ATM Control Point. Reversing the chip should solve the problem.
•Any VPD PROM that ships with an A02 WAN I/O card can be used with any of the other I/O cards without affecting card function. However, the card will not be listed properly in the configuration, which could be very confusing to someone managing the network. It is strongly advised that you carefully match the VPD PROM part numbers with their respective I/O cards as listed in Table 7 on page 69
