Hot Plug in High-Availability Applications
2.1.6
Hot Plug in High-Availability Applications
Hot Plug capability allows replacement of hardware modules and maintenance performance without
system power down.
The PEX 8532 Hot Plug capability and Advanced Error Reporting features make the PEX 8532 suitable
for High-Availability (HA) applications. Each downstream port includes a Standard Hot Plug controller.
If the PEX 8532 is used in an application where one or more of its downstream ports connects to PCI
Express slots, the individual port Hot Plug Controller is used to manage the Hot Plug event of its
associated slot. Additionally, the upstream port is a fully compliant Hot Plug client, and the PEX 8532
can be used on hot-pluggable adapter boards, backplanes, and fabric modules.
2.1.7
Fully Compliant Power Management
For applications that require power management, the PEX 8532 supports Link (L0, L0s, L1, L2/L3
Ready, and L3) and Device (D0 and D3hot) Power Management states, in compliance with the
PCI Express Base r1.0a Power Management specifications.
