Installing expansion card risers

An expansion card in the server is an add-on card that can be inserted into an expansion slot on the system board or riser card to add enhanced functionality to the system through the expansion bus.

* 
NOTE: A System Event Log (SEL) event is logged if an expansion card riser is unsupported or missing. It does not prevent your system from turning on and no BIOS POST message or F1/F2 pause is displayed.

Expansion card installation guidelines

Depending on your system configuration, the following PCI Express (PCIe) generation 3 expansion cards are supported:

Table 33. Supported expansion cards

Item 1 is the PCIe slot 1, on Riser 1 and is connected to Processor 2, it supports a low profile, half length 8x card. The slot width is 16x. Item 2 is the PCIe slot 2, on Riser 1 and is connected to Processor 2, it supports a low profile, half length 8x card. Item 3 is the PCIe slot 3, on Riser 1 and is connected to Processor 2, it supports a low profile, half length 8x card. The slot width is 16x. Item 4 is the PCIe slot 4, on Riser 2 and is connected to Processor 2, it supports a full height, full length 16x card. The slot width is 16x. Item 5 is the PCIe slot 5, on Riser 2 and is connected to Processor 1, it supports a full height, full length 8x card. The slot width is 16x. Item 6 is the PCIe slot 6, on Riser 3 and is connected to Processor 1, it supports a full height, full length 16x card. The slot width is 16x (alternate).

* 
NOTE: To use PCIe slots 1 through 4 on the risers 1 and 2, both the processors must be installed.
* 
NOTE: The expansion card slots are not hot-swappable.

The following table provides guidelines for installing expansion cards to ensure proper cooling and mechanical fit. The expansion cards with the highest priority should be installed first using the slot priority indicated. All the other expansion cards should be installed in the card priority and slot priority order.

* 
NOTE: Ensure that the 100 G OPA x16 card is installed in slot 6 (x16 PCIe) on the alternate riser 3.

Removing an expansion card from expansion card riser 2 or 3

* 
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product.
* 
CAUTION: When removing the NV-RAM card ensure that, after powering down the system gracefully from the GUI or CLI, both green and amber LEDs on the card are off.
1.
Follow the safety guidelines listed in the Safety instructions section.
2.
Follow the procedure listed in the Before working inside your system section.
3.
When removing a card from riser 3, ensure that the PCIe holder latch is closed.
1.
Disconnect any cables connected to the expansion card.
2.
Lift the expansion card latch out of the guide slot.
3.
Hold the expansion card by its edges, and remove it from the expansion card connector.
4.
If you are removing the card permanently, install a metal filler bracket over the empty expansion slot opening and close the expansion card latch.
* 
NOTE: You must install a filler bracket over an empty expansion card slot to maintain Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of the system and aid in proper cooling and airflow inside the system.
5.
Install the expansion card latch into the slot.
6.
Close the expansion card locking tabs.
