Maintenance Scenarios
Note Make sure that you replace the Cisco 170 series HDDs with Cisco supplied HDDs that are specific to
and preconfigured for the Cisco 170 series appliance. Please contact Cisco Technical Support for more
information or in case of an Return Merchandise Authorization (RMA). See the “Contacting Service and
Support” section on page 4-3.
You may need to install, remove, or replace a HDD in your Cisco 170 series appliance under the
following conditions:
• If a single drive fails, you can replace the failed drive. You can hot-swap the failed drive.
• If both drives fail simultaneously, you need to return the entire system via an RMA.
Note When you replace a drive, the disk indicator light is a blinking amber indicating a rebuild event. Once
the rebuild is completed, the disk indicator light changes to a flashing green.
Replacing the Hard Disk Drives
The Cisco 170 series appliance has two HDDs in a RAID 1 configuration. If one of the HDDs fails, you
can remove and install a new HDD.
Caution Make sure that you replace the failed hard disk drive as soon as possible; otherwise, if the remaining
hard disk drive fails, all your data is lost.
To remove and install (replace) hard disk drives in the Cisco 170 series appliance, follow these steps:
Step 1 From the front panel of the Cisco 170 series appliance, remove the hard disk drive by pressing the button
on the right side of the bay until the lever is released. Pull out the hard disk drive.
Figure 4-1 shows the Cisco 170 series appliance with two HDDs.
