For details, see "SRX1400 Services Gateway AC Power Supply" on page 33.
DC Power Supply (for SRX1400BASE-GE-DC and SRX1400BASE-XGE-DC models)
For details, see "SRX1400 Services Gateway DC Power Supply" on page 35.
The power supplies are located at the front of the chassis. Each AC power supply weighs
approximately 3.1 lb (1.4 kg). Each DC power supply weighs approximately 2.9 lb (1.3 kg).
NOTE: Only redundant power supplies (AC or DC) support hot-removable
and hot-insertable functionality.
The SRX1400 Services Gateway uses either one AC or one DC power supply unit. A second
AC or DC power supply can be used with its matching type of power supply to offer
redundancy. The power supplies connect to the backplane, which distributes 10 V main
power and 3.3 V standby power to the services gateway components. Each power supply
is cooled by its own internal cooling system.
CAUTION: Do not mix AC and DC power supplies within the same services
gateway. Damage to the device might occur.

AC Power Supply Overview

In an AC power configuration, the SRX1400 Services Gateway contains one or two AC
power supplies, located at the front panel of the chassis in slots
power supply provides power to all components in the services gateway. When two
power supplies are present, they share power almost equally within a fully populated
system. The two AC power supplies provide full power redundancy. If one power supply
fails or is removed, the remaining power supply redistributes the electrical load without
interruption.
Figure 14 on page 34 shows the SRX1400 Services Gateway AC power supply.
NOTE: Only redundant AC power supply supports hot-removable and
hot-insertable functionality.
