Working with Adapters

The WAE-7371, WAE-7341, and WAE-674 have connectors for up to four PCI adapters on the system board and PCI riser card.

Before you install an adapter, review the following information:

Locate the documentation that comes with the adapter and follow those instructions in addition to the instructions in this chapter. If you need to change the switch or jumper settings on your adapter, follow the instructions that come with the adapter.

PCI-X slots 1 and 2, on the riser card, support standard full-length adapters, such as the Cisco WAE Inline Network Adapter.

PCI Express slots 3 and 4, on the system board, support low-profile adapters, but are not used for any WAE adapters.

PCI-X slot 1 and slot 2 are 64-bit slots and support only 3.3-V and universal PCI adapters.

The PCI bus configuration is as follows:

Non-hot-plug, low-profile PCI Express x8 (x4 lanes), slot 4

Non-hot-plug, low-profile PCI Express x8 (x4 lanes), slot 3

Non-hot-plug, 64-bit PCI-X slot 2 (133 MHz)

Non-hot-plug, 64-bit PCI-X slot 1 (133 MHz)

The system scans PCI slots 1 through 4 to assign system resources. The system starts (boots) the system devices in the following order, if you have not changed the default boot precedence:

Integrated Ethernet controller

Integrated Serial Attached SCSI (SAS) controller

PCI slots 1, 2, 3, and 4.

For information about the features of the Cisco WAE Inline Network Adapter and its cabling requirements, see Chapter 5, "WAE Inline Network Adapter."

Installing an Adapter

To install a PCI-X adapter in the riser-card assembly, follow these steps:


Step 1 Review the information in the "Safety Warnings" section on page 2-1 and the "Safety Guidelines" section on page 2-4.

Step 2 Power down the device and peripheral devices and disconnect all power cords and external cables.

Step 3 Remove the cover. (See the "Removing the Cover" section.)

Step 4 Remove the PCI-X riser-card assembly. (See Figure 4-2.) Push the two riser-card assembly release tabs toward the PCI-X slots. Grasp the assembly at the rear and side edges and lift it to remove it from the WAE. Place the riser-card assembly on a flat, static-protective surface.

Step 2 Install the device in a rack.

For complete rack installation and removal instructions, see Chapter 3, "Installing the Wide Area Application Engine."


Caution Install the device only in a rack cabinet with perforated doors.


Caution Do not leave open spaces above or below an installed device in the rack cabinet. To help prevent damage to device components, always install a blank filler panel to cover the open space and to help ensure proper air circulation. See the documentation that comes with your rack cabinet for more information.

Step 3 Connect the cables and power cords. For information on connecting cables and power cords, see the "Connecting Cables" section on page 3-11.


Installing Memory in a WAE-674

The WAE-674 features 4 GB of RAM. You can install an additional 4 GB of RAM to give your WAE-674 a total of 8 GB of RAM. This section describes how to install the optional 4 GB memory upgrade, which includes two 2-GB DIMMs.

To install additional memory in your WAE-674, follow these steps:


Step 1 Review the information in the "Safety Warnings" section on page 2-1 and the "Safety Guidelines" section on page 2-4.

Step 2 Power off the device and all attached devices and disconnect all external cables and power cords.

Step 3 Remove the device top cover. See the "Removing the Cover" section.

Step 4 Remove the riser-card assembly as shown in Figure 4-6.

Figure 4-6 Accessing the DIMMs

Step 5 Remove the DIMM air baffle.

Step 6 Locate DIMM slots 7 and 10, as shown in Figure 4-7.

The standard memory for your WAE-674 is located in DIMM slots 1 and 4. You will install the two upgrade DIMMS in slots 7 and 10.

Figure 4-7 Locating the DIMM slots

Step 7 Open the retaining clip on each end of the DIMM connector for slots 7 and 10, as shown in Figure 4-8.

Figure 4-8 Inserting a DIMM into the slot

Step 8 Align each DIMM so that the key fits correctly with the connector.

Step 9 Insert each DIMM into the connector. Firmly press the DIMM straight down into the connector so that the retaining clips snap into the locked position.


Note If there is a gap between the DIMM and the retaining clips, the DIMM is not correctly inserted.


Step 10 Replace the DIMM air baffle.

Step 11 Replace the riser-card assembly.

Step 12 Reinstall the cover.

For instructions on completing the hardware installation, see the "Completing the Installation" section.

Step 13 Once the hardware installation has been completed, you must repartition the disks, using the disk delete-data-partitions command, and reload.

A BIOS system message displays indicating that the system memory has changed. Confirm the system memory change.


Note Repartitioning the disks is required after adding memory to reset the DRE space allocation.



Replacing a Hard Disk Drive

The WAE supports as many as six 1-inch (26-mm) slim, 3.5-inch hard disk drives installed on Ultra-Slim hard disk drive trays for 3.5-inch drives.

You can replace one disk drive at a time in the RAID-5 disk array. If multiple hard disks fail, the RAID-5 logical drive automatically goes into the Offline state.


Note All hard disk drives being used in the device must be identical.



Note The SCSI ID assigned to each bay is printed on the bezel.



Caution To maintain proper system cooling, do not operate the device for more than 10 minutes without either a hard disk drive or a filler panel installed in each bay.

To replace a hard disk drive in a bay, follow these steps:


Step 1 Review the information in the "Safety Warnings" section on page 2-1 and the "Safety Guidelines" section on page 2-4.

Step 2 Enter the disk disk-name diskxx replace command in EXEC mode at the WAAS CLI on the WAE.

Step 3 Verify that the disk drive diskxx is in the Defunct state by entering the show disks details command in EXEC mode. The RAID logical drive is in the Critical state at this point.

Step 4 Move the handle (see Figure 4-9) on the drive to the open position (perpendicular to the drive).

Figure 4-9 Replacing a Hard Disk Drive

Step 5 Pull the hot-swap drive assembly from the bay.

Step 6 Wait for 1 minute and then insert the new drive into the same slot by aligning the replacement drive assembly with guide rails in the bay and sliding the drive assembly into the bay until it stops. Make sure that the drive is properly seated in the bay.


Note Be sure there is no data on the replacement drive. The replacement hard drive should be new or newly-formatted.


Step 7 Close the drive handle.

Step 8 Check the hard disk drive status LED to verify that the hard disk drive is operating correctly. If the amber hard disk drive status LED for a drive is lit continuously, that drive is faulty and must be replaced. If the green hard disk drive activity LED is flashing, the drive is being accessed.

Step 9 Wait 1 minute and then verify that the replaced disk drive is in the Rebuilding state by using the show disks details command in EXEC mode.


Note The ServeRAID controller automatically starts the rebuild operation when it detects the removal and reinsertion of a drive that is part of the logical RAID drive.


Step 10 Wait until the rebuild operation is complete. You can check if the rebuild operation is complete by using the show disk details command in EXEC mode. The physical drive state will be Online and the RAID logical drive state will be Okay after the rebuild operation is completed.


A 300 GB SAS drive may take up to 5 hours to finish rebuilding.

If you have multiple disk failures and your RAID-5 logical status is Offline, you must recreate the RAID-5 array. For more information on disk removal and replacement procedures, see the Cisco Wide Area Application Services Configuration Guide, Chapter 15, "Maintaining Your WAAS System."

Replacing a Power Supply

The WAE supports two hot-swap power supplies.


Note If the device has two power supplies and you remove either of them, the device will not have redundant power; if the device power load exceeds 835 W, the device might not start or might not function correctly.



Warning Never remove the cover on a power supply or any part that has the following label attached.


Hazardous voltage, current, and energy levels are present inside any component that has this label attached. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician.


To replace a power supply, complete the following steps:

1. Disconnect the power cord from the AC power supply that you are removing.

2. Grasp the power supply handle.

3. Press the orange release latch down and hold it down.

4. Pull the power supply part of the way out of the bay, as shown in Figure 4-10.

Figure 4-10 Replacing a Power Supply

5. Release the release latch. Support the power supply underneath and pull it the rest of the way out of the bay.

6. Slide the replacement AC power supply into the bay until the retention latch clicks into place.

7. Connect the power cord for the new AC power supply to the power-cord connector on the power supply.

8. Route the power cord through the power-supply handle and through any cable clamps on the rear of the device to prevent the power cord from being accidentally pulled out when you slide the device in and out of the rack.

9. Connect the power cord to a properly grounded electrical outlet.

10. Make sure that the DC power LED and AC power LED on the power supply are lit, indicating that the power supply is operating correctly.
