DC Power Supply in Junos Space Appliances
This topic applies to the following Junos Space Appliances: JA1500 and JA2500.
A Junos Space Appliance ships with a single AC power supply module. However, you can
use a DC power supply, shown in
Figure 5 on page 17 , to power the appliance.
NOTE: While it is possible to provide redundancy in the Junos Space Appliance
using a combination of AC and DC power supply modules, we recommend
that you do not provide redundancy in this manner. Instead, use two DC power
supply modules or two AC power supply modules if you want to provide
redundancy.

Table 11 on page 17 shows details of the DC power supply module for a Junos Space
Appliance.
