Dell R740/R740XD Riser 1B, 3X8 for Riser Configs 1, 2, 5

Riser 1B supports slots 1, 2, and 3 through Processor 1, with slots 1 and 2 supporting full-height/full-length cards and slot 3 supporting a full-height/half-length card. This riser is typically used when replacing a missing or failed riser, restoring the correct expansion-card layout, or configuring an R740 or R740xd for supported PCIe hardware such as network adapters, storage controllers, HBAs, or other expansion cards. Compatibility depends on the server model, riser configuration, processor count, chassis layout, airflow/shroud configuration, and installed expansion hardware.
