LWC Chassis

Front Panel of an LWC Device

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)

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.

  3. Console port (accessible only to Juniper Networks resident engineers)

Rear Panel of an LWC Device

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).

Network Port and Uplink Port LEDs on an LWC Device

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.

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.
