370 IBM z13s Technical Guide
10.1 IBM z13s power and cooling
z13s servers have a number of options for installation on a raised floor, or on a non-raised
floor. Furthermore, the cabling can come into the bottom of the machine, or into the top of the
machine.
10.1.1 Power and I/O cabling
The z13s server is an air-cooled, one-frame system. Installation can be on a raised floor or
non-raised floor, with numerous options for top exit or bottom exit for all cabling (power cords
and I/O cables) as shown in Figure 10-1.

Top Exit I/O
Like the zBC12, z13s servers support the Top Exit I/O Cabling feature (FC 7920). This feature
routes all coupling links and all I/O cables, including a 1000BASE-T Ethernet cable from I/O
drawers or PCIe I/O drawers through two frame extensions, out the top of the frame.
