SRX5400 Chassis
SRX5400 Firewall Chassis
The firewall chassis is a rigid sheet metal structure that houses all the other components (see Figure 1, Figure 2, and Figure 3). The chassis measures 8.71 in. (22.1 cm) high, 17.45 in. (44.3 cm) wide, and 24.5 in. (62.2 cm) deep (from the front to the rear of the chassis). The chassis installs in standard 800-mm (or larger) enclosed cabinets, 19-in. equipment racks, or telco open-frame racks. Up to five firewalls can be installed in one standard (48 U) rack if the rack can handle their combined weight, which can be greater than 1100 lb (500 kg). See SRX5400 Firewall Physical Specifications for physical specifications for the SRX5400 Firewall.
Before removing or installing components of a firewall, attach an ESD strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap can result in damage to the firewall.
The firewall must be connected to earth ground during normal operation.

SRX5400 Firewall Midplane Description
The midplane is located toward the rear of the chassis and forms the rear of the card cage. MPCs, SPCs, and SCB install into the midplane from the front of the chassis, and the power supplies install into the midplane from the rear of the chassis. The cooling system components also connect to the midplane.
The midplane performs the following major functions:
Data path—Data packets are transferred across the midplane between the MPCs and SPCs through the fabric ASICs on the SCB.
Power distribution—The power supplies are connected to the midplane, which distributes power to all the firewall components.
Signal path—The midplane provides the signal path to the MPCs, SCB, SPCs, Routing Engine, and other system components for monitoring and control of the system.
The enhanced midplane supports Junos OS Release 15.1X49-D10. It provides greater per-slot fabric performance and signal integrity, along with error-free high speed data transfer, and it reduces cross-talk. The midplane supports link speeds up to 10 Gbps and is not field replaceable.
SRX5400 Firewall Craft Interface Overview
The craft interface shows you status and troubleshooting information at a glance and lets you perform many system control functions. It is hot-insertable and hot-removable. The craft interface is located on the front of the firewall above the upper fan tray.
Figure 4 shows the front panel of the craft interface and Table 2 describes the components on the front panel.

Component | Description | Reference |
---|---|---|
1 | Routing Engine LEDs | |
2 | Fan LEDs | |
3 | PEM LEDs | |
4 | Minor alarm LED | See SRX5400 Firewall Craft Interface Alarm LEDs and Alarm Cutoff/Lamp Test Button |
5 | Major alarm LED | |
6 | Alarm cutoff button | |
7 | Alarm relay contacts | |
8/9 | SCB and MPC LEDs, and MPC online/offline buttons The card LEDs are located along the bottom edge of the craft interface and are labeled 0 for the bottom slot reserved for the SCB and 0/1, 1, and 2 for the remaining slots. |
The SCB must be installed in the firewall for the craft interface to obtain power.
SRX5400 Firewall Craft Interface Host Subsystem LEDs
The host subsystem has three LEDs, located on the upper left of the craft interface, that indicate its status. The LEDs labeled RE0 show the status of the Routing Engine and SCB in slot 0 . The LEDs labeled RE1 are disabled and have no function. Table 4 describes the functions of the host subsystem LEDs.
Label | Color | State | Description |
---|---|---|---|
MASTER | Green | On steadily | Host is functioning as the primary. |
ONLINE | Green | On steadily | Host is online and is functioning normally. |
OFFLINE | Red | On steadily | Host is installed but the Routing Engine is offline. |
Off | Host is not installed. |
SRX5400 Firewall Craft Interface Power Supply LEDs
Each power supply has two LEDs on the craft interface that indicate its status. The LEDs, labeled 0 through 3, are located near the middle of the craft interface next to the PEM label. Table 5 describes the functions of the power supply LEDs on the craft interface.
Label | Color | State | Description |
---|---|---|---|
PEM | Green | On steadily | Power supply is functioning normally. |
Red | On steadily | Power supply has failed or power input has failed. |
SRX5400 Firewall Craft Interface Card OK/Fail LEDs
Each slot in the card cage has a pair of LEDs on the craft interface that indicates the status of the card installed in it. The card LEDs are located along the bottom edge of the craft interface and are labeled 0 for the bottom slot reserved for the SCB and 0/1, 1, and 2 for the remaining slots.Table 6 describes the functions of the OK and Fail LEDs.
Label | Color | State | Description |
---|---|---|---|
OK | Green | On steadily | The card is functioning normally. |
Blinking | The card is transitioning online or offline. | ||
Off | The card is not online. | ||
FAIL | Red | On steadily | The card has failed. |
SRX5400 Firewall Craft Interface Fan LEDs
The fan tray LED are located near the middle of the craft interface. Table 7 describes the functions of the fan tray LEDs.
Label | Color | State | Description |
---|---|---|---|
OK | Green | On steadily | Fan tray is functioning normally. |
FAIL | Red | On steadily | Fan tray has failed. |
SRX5400 Firewall Craft Interface Alarm Relay Contacts
The craft interface has two alarm relay contacts for connecting the device to external alarm devices (see Figure 5). Whenever a system condition triggers either the major or minor alarm on the craft interface, the alarm relay contacts are also activated. The alarm relay contacts are located on the upper right of the craft interface.

The alarm relay contacts consist of two sets of connectors, one set for each of the two alarms (major and minor). For each alarm color there are three connectors. Table 8 describes the functions of the connectors.
Contact Label | Contact Name | Function |
---|---|---|
NC | Normally Closed | Connects the alarm relay to an external alarm-reporting device that activates when the circuit between C and NC is closed. |
C | Current In | Connects the alarm relay to the current source for the external alarm-reporting device. |
NO | Normally Open | Connects the alarm relay to an external alarm-reporting device that activates when the circuit between C and NC is open. |
Table 9 shows the electrical specifications for the alarm relay contacts.
Current Type | ||
---|---|---|
AC | DC | |
Maximum Voltage | 250 | 30 |
Maximum Current | 8 A |
Figure 6 shows an example wiring diagram for a simple alarm reporting device. In this case the device is a 12-volt light bulb that illuminates when the device encounters a condition that activates the major alarm LED and relay contacts. The alarm relay contacts can also be used to activate other devices such as bells or buzzers.
