Mode Selector Button
The mode selector button is used to select the type of activity displayed on the LEDs labeled
1 through 48. 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.
10/100Base-T Ethernet Interfaces
The NetVanta 1238 PoE front panel contains 48 10/100Base-T Ethernet interfaces (RJ-45). These
interfaces are arranged in stacked pairs, with the numbers 1 through 48 screened directly above or
below the corresponding port. Status LEDs for each stacked pair are located directly over the
interfaces.
10/100/1000Base-T Gigabit Ethernet Interfaces
The NetVanta 1238 PoE front panel contains four Gigabit Ethernet interfaces (RJ-45). These interfaces
are labeled G1 through G4 and their status LEDs are located directly over the interfaces.
SFP Slots
The NetVanta 1238 PoE front panel contains two standard SFP slots for fiber connectivity. These
interfaces, numbered G1 and G2, are associated with the Gigabit Ethernet interfaces numbered G1 and
G2 and share status LEDs. (Use either the RJ-45 connectors or the SFP slots. The fiber slots have
precedence.)

configuration (via a DB-9 female connector).
Connection directly to an external modem requires a cross-over cable.
