EX-series Switch—LCD

The LCD on the front panel of an EX-series switch is a character display that can show two lines of text, each 16 characters in length. The LCD displays a variety of information about the switch and also provides a menu to perform basic operations such as initial setup and reboot (see Figure 1).

In an EX 3200 switch, the first line displays the host name. In an EX 4200 switch that is a member of a virtual chassis, the first line displays the virtual chassis ID, the role of the switch in a virtual chassis and the host name. The roles are indicated as RE for master, BK for backup, and LC for linecard.

The second line displays the mode of the network ports LED 2 (Figure 2) and the number of chassis alarms. The modes are: ADM (administrative status); DPX (duplex mode); POE (PoE status); and SPD (speed). You can change the mode using the Enter button.
