Replacing Memory Modules

This section describes how to remove and replace memory modules in the SteelFusion Edge appliances. This section includes the following procedures:

Replacing Memory Modules in 1U SteelFusion Edge Appliances

This section describes how to replace memory modules in SteelFusion Edge 2100 and SteelFusion Edge 2200 appliances. When replacing memory in the appliances, install the memory in the same slots.

The following diagram shows memory module slot locations in these appliances. (Figure 4‑12.)

To access the memory modules, you must remove the PCIe carriers. Remove the locking screws of the PCIe carrier on the back of the appliance. (Figure 4‑13.)

Lift the PCIe carrier straight out of the appliance using the attached strap. (Figure 4‑14.)

Remove the two screws securing the cooling shroud. Lift the cooling shroud straight up and out of the appliance. (See Figure 4‑15.)

Lift the shroud straight up to avoid damaging any components of the appliance.

Press the ejector tabs on the memory slots down and outward, and gently pull the memory module out of the slot. (Figure 4‑16.)

Remove the existing memory module and replace it with an approved memory module of the same size.

Align the memory-module edge connector with the slot alignment keys and insert it into the slot.

The module slot has two alignment keys that allow you to install the module in only one direction. (Figure 4‑17.)

Press down on the memory module with your thumbs until you hear it click.

Ensure that all ejector tabs are in the upright locked position.

Replacing Memory Modules in 2U SteelFusion Edge Appliances

This section describes how to replace memory modules in the SteelFusion Edge 3100, SteelFusion Edge 3200, and SteelFusion Edge 5100 appliances. When replacing memory in the appliances, install the memory in the same slots.

The following diagram illustrates memory module slot locations in these appliances. (See Figure 4‑18.)

To release the PCIe carrier, remove the two locking screws on the top of the carrier (see Figure 4‑19) and the one locking screw on the rear panel.

To remove the right and left PCIe carrier from the chassis, place your fingers in the carrier holes and lift straight up. (See Figure 4‑20.)

Figure 4‑20. Removing the PCIe Carriers from the Chassis

Remove the screws securing the cooling shroud to access the memory module slots. (See Figure 4‑21.)

Be careful not to damage any surrounding components when removing and installing the cooling shroud. Lift the shroud straight up to avoid damaging any components of the appliance.

Press the ejector tabs on the memory module slot down and outward and gently pull the memory module out of the slot. (See Figure 4‑22.)

Hold the memory module on the outside edges to prevent damage to the module. (See Figure 4‑23.)

Remove the existing memory module and replace it with an approved memory module of the same size. When adding memory, always replace the memory in the black slots first. Make sure the memory is equally distributed on both sides.

Replacing the existing memory module with a module of a different size is not recommended. Replace the failed memory module with the same memory module size. You must use approved memory modules. Contact Riverbed Support at https://support.riverbed.com to obtain the correct memory modules.

Align the memory-module edge connector with the slot alignment keys and insert it into the slot. The module slot has two alignment keys that allow you to install the module in only one direction. (Figure 4‑24.)

Press down on the memory module with your thumbs while pulling up on the ejectors with your index fingers to lock the module into the slot.

Ensure that all ejector tabs are in the upright locked position.

Repeat Step 6 to Step 11 to install the remaining memory modules.

To replace memory modules in a 2U SteelFusion Edge appliance with the QPI module installed

To release the PCIe carrier, remove the two locking screws on the top of the carrier (see Figure 4‑25) and the one locking screw on the rear panel.

To remove the right and left PCIe carrier from the chassis, place your fingers in the carrier holes and lift straight up. (See Figure 4‑26.)

Figure 4‑26. Removing the PCIe Carriers from the Chassis

Use extreme care when removing the QPI module. Damage to the module can cause unexpected results.

Remove the two small cooling shrouds by flipping them up and off of the module.

Unscrew the four screws on the QPI module. There are two on the top, one in the middle, and one at the bottom of the QPI module.

Carefully lift the QPI module up and remove it from the appliance.

Remove the screws securing the cooling shroud to access the memory module slots. (See Figure 4‑27.)

Be careful not to damage any surrounding components when removing and installing the cooling shroud. Lift the shroud straight up to avoid damaging any components of the appliance.

Press the ejector tabs on the memory module slot down and outward and gently pull the memory module out of the slot. (See Figure 4‑28.)

Hold the memory module on the outside edges to prevent damage to the module. (See Figure 4‑29.)

Figure 4‑30. Inserting the Memory Modules into the Connector Slot and Securing

Press down on the memory module with your thumbs while pulling up on the ejectors with your index fingers to lock the module into the slot.

Ensure that all ejector tabs are in the upright locked position.

Repeat Step 6 to Step 11 to install the remaining memory modules.
