6	`OK/FAIL`	Green—No issue with system power supply. Amber—Power failure or issue with one of the power supplies.

Interface Ports LEDs

HA Port LEDs

Each HA port has one Link activity LED below or above it. Figure 3 shows the location of the LEDs and Table 4 describes the LEDs.

Table 4: HA Port LEDs

LED	Description
Link activity LED	Solid green—A link is established. Off—There is no link established.

Management Port LEDs

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

Figure 4 shows the location of the LEDs on the management port and Table 5 describes the LEDs.

Table 5: Management Port LEDs

LED	Description
Link activity LED	Solid green—A link is established, but there is no activity on the link. Blinking green—There is link activity. Off—There is no link established.
Speed	Solid green—100-Mbps link is established. Solid amber—1000-Mbps link is established. Off—There is no link established.

Network Port LEDs

Each QSFP28 port has one link activity LED above it and each SFP+ port has one link activity LED located above or below it. Figure 5 shows the location of the LEDs and Table 6 describes the LEDs.

Table 6: Network Port LEDs

LED	Description
Link activity LED	Solid green—There is link activity. Off—There is no link established.

Port and Interface Numbering

Each port on the services gateway corresponds to a unique interface name in the CLI. The four Chassis cluster (HA) ports (referred to as PIC 0 ports of FPC 0), four 40/100-Gigabit Ethernet QSFP28 (quad small form-factor pluggable) ports (referred to as PIC 0 ports of FPC 1), and eight 1/10-Gigabit Ethernet SFP+ ports (referred to as PIC 1 ports of FPC 1). Figure 6 shows the SRX4600 Interface Port numbering.

In the syntax of an interface name, a hyphen (-) separates the media type from the FPC slot number (represented as an FPC in the CLI). The FPC slot number corresponds to the first number in the interface. The second number in the interface corresponds to the PIC number. The last number in the interface matches the port number on the PIC. Slashes (/) separate the FPC number from the PIC number and port number:

type-fpc/pic/port

type—Media type, which identifies the network device. For example:
- ge—Gigabit Ethernet interface
- so—SONET/SDH interface
- xe—10-Gigabit Ethernet interface
For a complete list of media types, see Interface Naming Overview.
fpc—FPC number, 0 or 1.
pic—PIC number, 0 or 1.
port—Port number.

The maximum capacity of an SRX4600 Services Gateway is 400 Gbps, which cannot be oversubscribed. In SRX4600, the network ports are available in two groups (referred to as PICs), with restrictions around the number and type of ports that can be configured without over-subscribtion.

Table 7 lists the different port configurations you can have on SRX4600.

Interface Options	PIC0				PIC1
Interface Options	1/0/0	1/0/1	1/0/2	1/0/3	1/1/0	1/1/1	1/1/2	1/1/3	1/1/4	1/1/5	1/1/6	1/1/7

2	100G	100G	4x10G or 1x40G	4x10G or 1x40G	1G or 10G	1G or 10G	1G or 10G	1G or 10G	1G or 10G	1G or 10G	1G or 10G	1G or 10G
3	100G	100G	100G	100G	-	-	-	-	-	-	-	-
