Chapter
Replacing Hard Drives
This section includes the following information:
•
Drive Population Guidelines, page 3-4
•
Drive Replacement Procedure, page 3-5
Note
You can only replace a failed drive. You cannot insert an addition drive. Additional user-installed drives
will not be recognized by the system.
Drive Population Guidelines
The Cisco 380 and Cisco 680 series appliance includes up to eight small form-factor (SFF) drives, with
a 24-drive backplane and expander. However, the various models of the Cisco 380 and Cisco 680 series
appliance only support the use of between two to eight of the slots for the hard drives.
Note
None of the models support more than eight hard drives. Because each model supports a different
maximum number of hard drives, see the
“Hardware and Technical Specifications” section on page A-2
for the number of hard drives supported by each specific model.
The drive-bay numbering is shown in
. It shows twenty-two hard drives, which is much more
than the number supported by any model of the Cisco 380 and Cisco 680 series appliances.
Figure 3-1
Drive Numbering, Small Form-Factor Drives
Observe these drive population guidelines for optimal performance:
•
None of the models support the use of drives in slots 10 through 23. The front bezel latches cover
two of the drive slots (slot 1 and slot 24).
•
You cannot install more drives than the number supported for your model. You can only replace
drives that are no longer working.
•
When you replace a drive, you must use the same slot as the drive that you replaced.
•
Do not remove the panels that cover empty drive slots.
