I/O expansion options
The server supports up to five PCIe slots with different riser cards installed into two riser sockets on the 
system planar (one riser socket supports the installation of one riser card). There are two types of riser 
cards: 2U risers and 1U risers. 2U risers are used in x3630 M4 models that do not have the rear HDD 
cage assembly (see Figure 4). 1U risers are used in models with the rear HDD cage assembly installed 
(see Figure 5). See Figure 4 and Figure 5 for slot locations and numbering.
Note: You cannot use 1U risers in models without the rear HDD cage. You cannot use 2U risers in models 
with the rear HDD cage assembly installed.
