2.5-inch drive backplane (signal)
Use the section to understand the cable routing for signal cable connections for 2.5-inch drive backplanes.
Notes: For the server with a performance heat sink (T-shape), remove the heat sink before disconnecting or 
connecting the cables which connect to PCIe 1, PCIe 2, PCIe 3, PCIe 4, PCIe 5, or PCIe 6 connectors (see 
the table below). After disconnecting or connecting the cables, install the heat sink back to the server. See 
“Remove a heat sink” on page 148 and “Install a heat sink” on page 151.
