Chapter 4 Installing Hardware Options for the WAVE-7541, WAVE-7571, and WAVE-8541
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.
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.

Step 3

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.
