10/100Base-T Ethernet Interfaces
The NetVanta 1238P 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.
100/1000Base-T Gigabit Ethernet Interfaces
The front panel contains two 100/1000Base-T Gigabit Ethernet interfaces (RJ-45) labeled G1 and G2 .
Status LEDs G1 and G2 are shared with SFP slots G1 and G2 and are located on the upper right corner
of the unit.
SFP Slots
The front panel contains four standard SFP slots for fiber connectivity numbered G1 through G4 with
Status LEDs located on the upper right corner of the unit. SFP slots G1 and G2 are associated with the
Gigabit Ethernet (RJ-45) interfaces numbered G1 and G2 and share status LEDs. (Use either the RJ-45
connectors for up 100/1000 Mbps copper connectivity or the SFP slots for 1 Gbps fiber connectivity.
The SFP slots have precedence.) Slots
G3 and G4 provide fiber connectivity at 1 or 2.5 Gbps.

CONSOLE Interface
The CONSOLE interface is an EIA-232 serial port (DCE) that provides local management and
configuration (via a DB-9 female connector).
Power Connection
The rear panel has a power input to the AC universal power supply. Please refer to Supplying Power to
the Unit on page 26 for connection details.
Connection directly to an external modem requires a cross-over cable.
