Replacing a PCIe Card

Caution Cisco supports all PCIe cards qualified and sold by Cisco. PCIe cards not qualified or sold by Cisco are the responsibility of the customer. Although Cisco will always stand behind and support the C-Series rack-mount servers, customers using standard, off-the-shelf, third-party cards must go to the third-party card vendor for support if any issue with that particular third-party card occurs.

This section includes the following topics:

PCIe Slots

The server contains two toolless PCIe risers for horizontal installation of PCIe cards. See Figure 3-21and Table 3-7for a description of the PCIe slots on these risers.

Note In a single-CPU system, PCIe riser 2 (slot 2) is not available.

Figure 3-21	Rear Panel, Showing PCIe Slots
	PCIe 2	PCIe 1
PSU 1		285208

	Table 3-7	PCIe Expansion Slots
	Electrical		Card Length1	Card Height 2	NCSI3 Support
Slot Number	Lane Width	Connector Length
1 (on riser 1)	Gen-3 x16	x16 extended	1/2 length	Full-height	Yes4
2 (on riser 2)	Gen-3 x16	x16 connector	1/2 length	1/2 height	No

1.This is the supported length because of internal clearance.

2.This is the size of the rear panel opening.

3.Network Communications Services Interface protocol

4.Slot 1 can operate when the server is in standby power mode.

Note In single-CPU configurations, only PCIe slot 1 can be used.
