JCS1200 Switch Module Components and LEDs
Figure 1 shows the components on the switch module.
Figure 1: JCS1200 Switch Module Components
The switch module consists of the following components:
- One RS-232 console port that provides an additional means to install software and configure the switch module. This USB-style connector enables connection of a special serial cable to the switch module.
- Six external copper 1000Base-T Ethernet ports for 10/100/1000 Mbps connections to the T Series router. These ports are identified as EXT1, EXT2, EXT3, EXT4, EXT5, and EXT6 in the switch configuration menus and are labeled 1 through 6 (from top to bottom) on the switch module. You can use RJ-45 ports labeled 1 through 3 to connect up to three T Series routers running JUNOS Release 9.2 and later to the JCS1200 platform. The RJ-45 ports labeled 4 and 5 on the switch module are reserved for future use. You can use the RJ-45 port labeled 6 to manage the switch module.
- Eight LEDs that indicate the status of the switch module and the network (see Figure 2).

The functions of the switch module LEDs are described in Table 1.
Table 1: JCS1200 Switch Module LEDs
Name | Color | State | Description |
|---|---|---|---|
OK | Green | On steadily | The switch module has passed the power-on self-test (POST) with no critical faults and is operational. |
Gigabit Ethernet switch module error (fault) (!) | Amber | On steadily | The switch module has failed the POST or detected an operational fault. Note: When the Gigabit Ethernet switch module error LED is lit, the system-error LED on the alarm panel is also lit |
Ethernet link (LINK) | Green | On steadily | There is a connection (or link) to a device using that connector. |
Ethernet activity (Tx/Rx) | Green | Flashing Note: The flash frequency is proportional to the amount of traffic on the network link. | Data is being transmitted or received (that is, activity is occurring) between that port and another device on the network link. |
