This is the rear PCIe filler for the R740 and R740xd servers. It takes the place of risers 2 and 3. In the absence of these risers you install this blank so there’s not a gaping hole in the rear of your server. This prevents junk from entering the server and maintains correct air flow throughout the chassis.
Common power supply for the Dell PowerEdge R430 and R440 servers. This power supply installed into an R440 8 Bay chassis.
This is a fan module for the HP DL 325 G10 server. It attaches to the motherboard via cable. It appears to be specific to this chassis.
This is what I consider the second variation of Riser 1 for the R740 and R740xd platforms. There are a total of 3 variations. This riser has 2 x16 slots. It’s longer than the first variation, has less slots, but does include x16 slots which the first variation does not.
There are 3 variations of Riser 1 for the Dell PowerEdge R740. This variation is the shortest riser and allows for installation of a mini RAID controller. Longer variations take up the slot as explained in this post.
This particular riser has 3 x8 slots. It lacks a x16 so keep that in mind.
