Руководство По Установке для Cisco Cisco Email Security Appliance C170

 lists the specifications for each 650 W AC power supply.

Disk Drives

Disk drives are installed into front-panel drive bays that provide hot-pluggable 
access. All appliances have small form-factor (SFF) drives, with a 24-drive 
backplane and expander. Because the front latch bezels cover two drive slots, the 
appliance holds up to twenty-two 2.5-inch hard drives.

You cannot use all twenty-two of the hard drive slots. The maximum 
number of hard drives that are supported are listed below for each model. 

Cisco C380 Email Security appliance includes two (2) 600 G HDDs.

Cisco C680 Email Security appliance includes six (6) 300 G HDDs.

Cisco M380 Content Security Management appliance includes four (4) 
600 G HDDs.

Cisco M680 Content Security Management appliance includes eight (8)
