rear five PCI-E modules,
sixteen are in the eight front CPU modules, two are inside
the storage module.
4.3.6.6 The Rear Five PCI-E Modules
Each module can support one FHHL PCI-E 3.0 x16 card, which features a hot-plug*
capability for adding and removing PCI-E cards.
4.3.6.7 The Front Eight CPU Modules
Each CPU module has two PCI-E bays, and together to support the one of the
following
configurations:
Up to sixteen full-height (FH) PCI-E 3.0 x16 cards
Up to eight GPUs plus 16 U.2 NVMe drives or eight full-height (FH) PCI-E
3.0 x16 cards
Up to thirty-two U.2 NVMe drives
4.3.6.8 Inside the Storage Module
The storage module supports two low-profile (LP) PCI-E 3.0 x8 (in x16 slot) internal
cards,
or one full-height (FH) PCI-E 3.0 x8 (in x16 slot) internal cards via riser for OEM.
4.3.6.9 PCIE Module
Perform the following steps to replace a PCI-E card in one of five hot-plug PCI-E
modules at the rear of the system while the system is on.
Note : Both the OS and PCI-E card must support the hot-plug feature.
4.3.6.10 Removing a Hot-Plug PCI-E Card
1. Initiate a hot-removal request by pushing the Attention Button on the
corresponding slot. The green power LED will blink to indicate the module is in
a transition state. (To cancel the hot-plug removal operation, press the
Attention Button again within five seconds.)
2. The power LED will turn off, showing that it is safe to remove the module. If
not, it indicates the request has failed (possibly due to client's software
unwilling to relinquish the device).
