Working with Adapters
Caution
For proper cooling and airflow, replace the cover before turning on the device.
Operating the device for extended periods (over 30 minutes) with the cover
removed might damage device components.
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

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 on page 4-1.)
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.

Make sure that cables are not routed on top of components under the PCI-X
riser-card assembly.
Make sure that cables are not pinched by the device components.
Step 9
Carefully align the riser-card assembly with the release tab posts, the guides on
the rear of the WAE, and the riser-card connector on the system board. Press down
on the assembly. (See Figure 4-4.) Make sure that the riser-card assembly is fully
seated in the riser-card connector on the system board.

Installing Memory in a WAE-674
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 on page 4-1.
Step 4
Remove the riser-card assembly as shown in Figure 4-6.

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 on page 4-8.
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.

Replacing a Hard Disk Drive
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).

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.

Replacing a Power Supply
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
Never remove the cover on a power supply or any part that has the following
label attached.
185095
Warning
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.
