LCD Panel in EX 3200 and EX 4200 Switches

LCD Panel in EX 3200 and EX 4200 Switches

The LCD panel on the front panel of EX 3200 and EX 4200 switches shows two lines of text, each a maximum of 16 characters in length. The LCD panel 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 hostname. 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 hostname. The roles are indicated as RE for master, BK for backup, and LC for linecard member.

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