Removing a PCIe Card

You need to remove a Peripheral Component Interconnect Express (PCIe) card before replacing it with a new one.

Scenarios

Remove a PCIe card in any of the following scenarios:

  • A PCIe card fails.
  • A PCIe card needs to be replaced with a new model.

Figure 5-15 shows the positions of the PCIe card on the CH222.

Prerequisites

Conditions

Data

N/A.

Tools

  • Electrostatic discharge (ESD) gloves.
  • M3 Phillips screwdriver.
  • Packaging materials, for example, an ESD bag.

Procedure

  • Remove a full-height half-length PCIe card.
  1. Use a Phillips screwdriver to loosen the two screws on the PCIe card tray and remove the PCIe card from the connectors on the mainboard. See steps (1) and (2) in Figure 5-16.
