Power down the appliance.
Note You must power down the appliance before installing or removing an Interface Module. Interface
Modules are not hot-swappable.
Step 3 Locate the Interface Module slot in the appliance chassis and slide the Cisco Interface Module into the slot until the ejector lever is seated.
To remove an Interface Module, first use the ejector lever to unlatch and then pull out the Interface
Module. (See
Figure 4-1 .)

Replacing a Hard Disk Drive/Solid State Drive
Note The WAVE-594 and WAVE-694 support both Hard Disk Drives and Solid State Drives, but you cannot mix HDD and SSD in the same chassis. For details about the WAVE-594 and WAVE-694 appliance specifications, see
Appendix A, “Appliance Specifications”
.
Replacing a Hard Disk Drive
Hard drives are hot-swappable therefore it is not necessary to power the system down before installing or replacing.
When removing hard drives from the WAVE appliance, observe the following general guidelines:
• The system automatically sets all drive numbers.
• Drives must be the same capacity to provide the greatest storage space efficiency when drives are grouped together into the same drive array.
Note All hard disk drives being used in the appliance must be identical.
Note The HDD should not be replaced with SSD when WAVE is in CM device mode, as it is not supported.
Caution To maintain proper system cooling, do not operate the appliance for more than 1 minute 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:

Press the button and swing the handle out. (See Figure 4-2
).
Note Wait 5 seconds before removing to let the disk spin down.

After waiting 5 seconds, pull the handle to remove the drive assembly from the bay.
Within one minute, 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.
Close the drive handle.
Check the hard disk drive status LED after the system has booted 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.
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 system automatically starts the rebuild operation when it detects the removal and reinsertion of a drive that is part of the logical RAID drive.
Step 8
Step 9
Wait until the rebuild operation is complete. A disk rebuild operation may take several hours. 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.
Use the show disk tech command in EXEC mode to verify that the firmware and BIOS information is correct for both hard drives.
If you have multiple disk failures and your RAID-1 logical status is Offline, you must recreate the
RAID-1 array. For more information on disk removal and replacement procedures, see the Cisco Wide
Area Application Services Configuration Guide chapter named “Maintaining Your WAAS System.”
Replacing a Fan
The WAVE appliance supports six fan assemblies that are hot-swappable.
