Guidelines
You can install a PCIe module in a PCIe slot for a larger-sized PCIe module. For example, an LP
PCIe module can be installed in a slot for an FHFL PCIe module.
A PCIe slot can supply power to the installed PCIe module if the maximum power consumption of the
module does not exceed 75 W. If the maximum power consumption exceeds 75 W, a power cord is
required.
If a processor is faulty or absent, the corresponding PCIe slots are unavailable. For more information
about processor and PCIe slot mapping relationship, see "Riser cards."
Prerequisites
Take the following ESD prevention measures:
•
Wear antistatic clothing.
•
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
•
Do not wear any conductive objects, such as jewelry or watches.
When you replace a component, examine the slot and connector for damages. Make sure the pins
are not damaged (bent for example) and do not contain any foreign objects.
Removing a riser card and a PCIe module
1. Power off the server. For more information, see " Powering off the server ."
2. Remove the server from the rack. For more information, see " Removing the server from a rack ."
3. Remove the access panel. For more information, see " Removing the access panel ."
4. Remove the chassis air baffle.
5. Disconnect all cables that hinder the replacement, if any.
6. Remove the riser card installed with a PCIe module:
a. Remove the riser card. Slide the locking tab to release the locking lever.
b. Lift the locking lever, and then lift the riser card out of the chassis to remove the riser card.
7. Remove the PCIe module from the riser card. Open the retaining latch of the riser card, and
then pull the PCIe module out of the slot.
Installing a riser card and a PCIe module
1. Install the PCIe module on the riser card:
a. Open the retaining latch of the riser card.
b. Remove the PCIe module blank.
c. Install the PCIe module to the riser card. Insert the PCIe module into the PCIe slot along the
guide rails, and then close the retaining latch.
2. Install the riser card on the server:
a. Unlock the riser card. Slide the locking tab to release the locking lever.
b. Insert the riser card into the PCIe riser connector along the guide rails, and then, close the
locking lever. The riser card will automatically slide into place.
WARNING!
For the riser card to be installed correctly, press the connector of the riser card after the
locking lever is closed.
