Each pin in the J1 and J2 connectors is rated for 2 amps, but the
N9377A load card is rated for 7.5 amps. You can accommodate
higher amperage loads by sharing pins on the connector. (Notice
in the wiring schematic,
J1 and J2 are connected together on the PC board.) When
connecting high-current (>2 amp) loads, wire across all five pins
in each row of the connectors (see
current sharing across all pins and prevents premature pin
failure from the excessive current flow.
Connecting high-current (>2 amp) loads without wiring across all
five pins in the row can cause premature pin failure.

As with the E6176A 16-channel load card, you can mount the
loads externally on a metal plate that fits into the SLU slots
adjacent to the load card. For guidelines on mounting loads
