SRX4100 Power System
SRX4100 Power Supply
The SRX4100 Firewall is shipped with two AC or two DC power supply units preinstalled in the rear panel. Each power supply provides power to all components in the services gateway. If one power supply fails or is removed, the remaining power supply redistributes the electrical load without interruption. Each power supply is cooled by its own internal cooling system.
AC Power Supply
Each AC power supply weighs approximately 2.3 lb and consists of one AC appliance inlet, a fan, and LEDs for monitoring the status of the power supply. The AC power supply is a hot-insertable and hot-removable field-replaceable unit (FRU) when the second power supply is installed and running. You can install the replacement power supply without powering off the services gateway. The AC power supply gives an output of 650 W and supports both low line voltage (100–127 VAC) and high line voltage (200–240 VAC). Figure 1 shows the AC power supply.
Figure 2 shows the location of the LEDs on an AC power supply. Each AC power supply faceplate contains three LEDs that indicate the status of the power supplies.
Table 1 describes the AC power supply LEDs.
LED |
Color |
State |
Description |
---|---|---|---|
AC |
Unlit |
Off |
Indicates one of the following:
|
Green |
Steady |
Input power present and is within the normal operating range. |
|
DC |
Unlit |
Off |
No DC power output or abnormal DC output. |
Green |
On steadily |
DC power output is within the normal operating range. |
|
! (Fault) |
Amber |
On steadily |
Power supply unit failure. |
Blinking |
Invalid power supply unit. |
||
Unlit |
Off |
Power supply unit is functioning normally. |
If both the AC LED and the DC LED are unlit, either the AC power cord is not installed properly or the power supply fuse has failed.
If the AC LED is lit and the DC LED is unlit, the AC power supply is installed properly, but the power supply has an internal failure.
DC Power Supply
Each DC power supply weighs approximately 2.2 lb and has two independent pairs of DC input lugs, a fan, and LEDs for monitoring the status of the power supply. The DC power supply in the services gateway is a hot-insertable and hot-removable field-replaceable unit (FRU) when the second power supply is installed and running. You can install a replacement power supply without powering off the services gateway. The DC power supply gives an output of 650 W. Figure 3 shows the DC power supply.
The DC power supply requires a dedicated circuit breaker rated for 9 A (–48 VDC) minimum, or as required by local code.
Figure 4 shows the location of the LEDs on a DC power supply. Each DC power supply faceplate contains three LEDs that indicate the status of the power supplies.
Table 2 describes the DC power supply LEDs.

AC Power Cord Specifications for the SRX4100 Services Gateway
A detachable AC power cord is supplied with the AC power supplies. The coupler is type C13 as described by International Electrotechnical Commission (IEC) standard 60320.
In North America, AC power cords must not exceed 4.5 m (approximately 14.75 ft) in length, to comply with National Electrical code (NEC) Section 400-8 (NFPA 75, 5-2.2) and 210-52, and Canadian Electrical Code (CEC) Section 4-010(3).
Table 4 provides power cord specifications, and Figure 5 depicts the plug on the AC power cord provided for each country or region.
