WARNING

J5 Debug Connector is not compliant to PMC component height specification. It should be removed to insert the 4538 and its carrier into a CompactPCI chassis.

ISP Enable Jumper JP1

The 4538 includes a location for a jumper at JP1. This location is used during production to enable the programming of the card’s EPLD programmable devices “in-situ”. This location should never be used by the normal user.

Blank Card Jumper JP2

Location for a jumper at JP2 is needed for production when the PowerSPAN serial EEPROM is not yet programmed, in order to prevent the card from locking the system. This location should never be populated with a jumper by the normal user.
