LWC Chassis

The LWC does not use all the ports available on its front panel. It uses only the following ports:

• One 1GbE RJ-45 network port (port 0, interface name ge-0/0/0) used to access the captive portal (for configuration and diagnostics)
• Two 1GbE/10GbE SFP+ uplink ports (xe-0/0/12 and xe-0/0/13 ) to connect the device to the internal and external networks
• The console (CON) port (accessible only to Juniper Networks resident engineers for troubleshooting purposes only)

Figure 1 shows all the components that are available on the front panel of an LWC device. Only the ports that are used are marked in the illustration.

1. 1GbE RJ-45 network port (only the port 0) used to access the captive portal (for configuration and diagnostics)
2. 1GbE/10GbE SFP+ uplink ports (connects the LWC to the internal and external networks)
3. Console port (accessible only to Juniper Networks resident engineers)

The rear panel of an LWC device consists grounding points, an electrostatic discharge (ESD) point, exhaust vents, a power switch, and an AC power cord inlet (see Figure 2).

Each network port and uplink port on the front panel of an LWC device has two LEDs that indicate link activity and port status (see Figure 3).

Table 1 describes the link activity LED.

Table 1: Link/Activity LED on the Network Ports and Uplink Ports in LWC Devices

LED	Color	State and Description
Link/Activity	Green	Blinking—The port and the link are active, and there is link activity. On steadily—The port and the link are active, but there is no link activity. Off—The port is not active.
