Questions about this item

What form factor does the DPS-550LB D power supply use for mounting in a Lenovo RD540?

The unit follows the ATX form factor, so it fits the standard PSU bay and screw pattern used in the Lenovo RD540, RD640 and RD630 chassis.

Which connector must be seated first when installing this 550W unit in a Lenovo RD640, and what is the common mistake?

Insert the main 24-pin ATX connector fully until the latch clicks; the frequent error is leaving it partially seated, which prevents the server from posting.
