NetVanta 1234 PoE Front Panel Features
Status LED
The STAT LED indicates the unit’s status and the LEDs are located on the lower left corner of the unit.
Mode Selector Button
The mode selector button is used to select the type of activity displayed on the LEDs labeled
1 through 24. If LINK/ACT is selected, the LEDs display the link status/activity of the ports. If PoE is
selected, the LEDs display the status of PDs connected to the ports.
CONSOLE Interface
The CONSOLE interface is an EIA-232 serial port (DCE) that provides for local management and
configuration (via a DB-9 female connector).
10/100Base-T Ethernet Interfaces
The NetVanta 1234 PoE front panel contains 24 10/100Base-T Ethernet interfaces (RJ-45). These
interfaces are arranged in stacked pairs, with the numbers 1 through 24 screened directly above or
below the corresponding port. Status LEDs numbered 1 through 24 are located in the LED bank on the
left side of the unit.
Connection directly to an external modem requires a cross-over cable.
