SRX4100 Chassis

SRX4100 Services Gateway Chassis Overview

The 4100 Services Gateway chassis is a rigid sheet metal structure that houses all the other hardware components. The chassis measures 1.75 in. high, 17.48 in. wide, and 25 in. deep. The chassis installs in standard 600-mm deep (or larger) enclosed cabinets or 19-in. equipment racks.

CAUTION:

Before removing or installing components of a functioning services gateway, attach an electrostatic discharge (ESD) strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the device.

The services gateway must be connected to earth ground during normal operation.

SRX4100 Firewall Front Panel

Figure 1 shows the front panel of the SRX4100 Firewall.

Figure 1: SRX4100 Firewall Front Panel

Table 1 lists the components on the front panel of the services gateway.

Table 1: SRX4100 Firewall Components on the Front Panel
Number	Component	Description
1	Management port	Gigabit Ethernet port to connect to the device over the network.
2	USB ports	Two USB 2.0 ports that accept a USB storage device.
3	HA ports	Two 1-Gigabit Ethernet/10-Gigabit Ethernet ports, CTL (control port) and FAB (fabric port), to synchronize data and maintain state information in a chassis cluster setup. These ports support enhanced small form-factor pluggable (SFP/SFP+) transceivers.
4	SFP+ ports	Eight 1-Gigabit Ethernet/10-Gigabit Ethernet SFP+ ports for network traffic. Note: Ports 0/0 to 0/3 are part of a port group that is connected to one CPU socket. Similarly, ports 0/4 to 0/7 form another port group and are connected to a different CPU socket. When choosing ports for network traffic, ensure that you use the ports equally from each socket so that the traffic is evenly distributed, and the overall CPU load is balanced. For example, if you plan to use two ports, then choose one port from each socket. If the network traffic passes only through the ports in one group, you might encounter performance and load balancing issues.
5	LEDs	Indicate component and system status at a glance.
6	Console port	Connects a laptop to the services gateway for CLI management. The port uses an RJ-45 serial connection, is configured as DTE, and supports the RS-232 (EIA-232) standard.
7	Reset button	Returns the services gateway to the factory-default configuration.

Chassis Status LEDs

Figure 2 shows the LEDs on the front panel, and Table 2 describes the LEDs.

Figure 2: SRX4100 Firewall Front Panel LEDs

Table 2: SRX4100 Firewall Front Panel LEDs
LED	Description
Power	Solid green—receiving power
Status	Solid green—operating normally Solid red—critical alarm Hardware component failure Software module failure Fan failure (atleast one) Blinking red—noncritical alarm The other HA node is in the lost, disabled, or ineligible state. Off—the system is not receiving power
SSD	Blinking green—indicates hard disk drive (SSD) activity

Management Port LEDs

The management port has two LEDs that indicate link activity and status of the management port.

Table 3 describes the LEDs.

Table 3: Management Port LEDs
LED	Description
Link/Activity (LED on the left)	Solid amber—A link is established, but there is no activity on the link. Blinking amber—There is link activity. Off—There is no link established.
Speed (LED on the right)	Solid green—100-Mbps link is established. Solid amber—1000-Mbps link is established. Off—There is no link established.

HA Port LEDs

Each HA port has one status LED located between the ports. Figure 3 shows the LEDs. The upper LED (callout 1) displays the status for the port on the right and the lower LED (callout 2) displays the status for the port on the left. Table 4 describes the LEDs.

Figure 3: HA Port LEDs

Table 4: HA Port LEDs
LED	Description
Status LED	Solid amber—A link is established. Blinking amber—There is link activity. Off—There is no link established.

Network Port LEDs

Each SFP+ port has two status LEDs located above the port. Table 5 describes the LEDs. Figure 4 shows the LEDs.

Figure 4: Network Port LEDs

Table 5: Network Port LEDs
Callout	LED	Description
1	Link (LED on the left)	Solid green—There is link activity. Off—There is no link established.
2	Speed/Activity (LED on the right)	Solid amber—10 G/1 G link is established. Blinking amber—There is activity on the 10 G/1 G link. Off—There is no link established.

SRX4100 Firewall Back Panel

Figure 5 shows the back panel of the SRX4100 Firewall, and Table 6 lists and describes the back panel components.

Figure 5: SRX4100 Firewall Back Panel

Table 6: SRX4100 Firewall Back Panel Components
Number	Component	Description
1	Grounding point	Connects the services gateway chassis to earth ground.
2	Power switch	Use the Power switch to power on or power off the services gateway.
3	Alarm Off button	Use this button to turn off an alarm triggered because of an abnormal DC output voltage caused by any of the following: Only one power supply unit is plugged in. The AC power cord is not plugged in. The power supply unit is not functional and there is no DC output.
4	ESD point	For personal safety, while working on the services gateway, use the ESD outlet to plug in an ESD grounding strap to prevent your body from sending static charges to the services gateway.
5	Fan trays	Four fan trays for cooling the services gateway and its components. Each fan tray contains two fans. Three fan trays are required for proper air flow across the chassis internal components. The fourth fan tray provides redundancy.
6	Power supply	Two power supply slots. Each power supply contains a power cord outlet. Two 650-W DC or AC power supplies are provided with the services gateway.
