1. INTRODUCTION
The NetVanta 1230 Series includes the NetVanta 1234, NetVanta 1234 Power over Ethernet (PoE),
NetVanta 1238, and NetVanta 1238 PoE.
This hardware installation guide lists the NetVanta 1230 units’ specifications, describes the physical
characteristics of the units, introduces basic functionality, and provides installation instructions.
2. PHYSICAL DESCRIPTIONS
NetVanta 1230 Series
The NetVanta 1230 and NetVanta 1230 PoE Series are managed switches housed in 1U-high rack-mountable
metal enclosures that include a universal AC power supply. The front panels contain 24 (NetVanta 1234 Series)
or 48 (NetVanta 1238 Series) 10/100Base-T Ethernet interfaces and four 10/100/1000Base-T Gigabit Ethernet
interfaces all accessed via standard RJ-45 connectors. Two industry standard small form-factor pluggable (SFP)
slots (supporting industry standard SFP modules) are available for high-speed uplink via fiber. NetVanta 1230
units run the ADTRAN Operating System (AOS), and are managed through an EIA-232 CONSOLE port
(DB-9) located on either the front or rear panel, Telnet session, or Web-based graphical user interface
(GUI). The NetVanta 1230 is RoHS compliant.
Power over Ethernet
The NetVanta 1230 Series PoE switches provide the same basic functionality as the standard product. PoE
provides the ability to detect attached powered devices (PDs), and deliver 48 VDC to the PD via existing CAT 5
cabling. The PoE switches are fully compliant with the IEEE 802.3af PoE standard. By default, the PoE
switches discover and provide power to IEEE-compliant PDs. NetVanta 1230 Series PoE switches support
legacy PoE.
SFP Module Slots
The NetVanta 1230 Series devices support two SFP slots that accept a number of industry standard SFP
modules. The SFP modules provide Gigabit Ethernet fiber connectivity for high-speed uplinks or switch
stacking. The following modules are available for purchase (both of these modules require fiber optic cable with
LC connectors):
• 1200480E1 1000Base-SX Multi-Mode SFP Module
• 1200481E1 1000Base-LX Single-Mode SFP Module
In this document, the term NetVanta 1230 means all of the units collectively. If a statement
only applies to one particular switch, the text refers to that switch individually.

Status LED
The STAT LED indicates the unit’s status and is located to the lower left corner of the unit.
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 front panel contains 24 10/100Base-T Ethernet interfaces (RJ-45). These interfaces
are arranged in stacked pairs, with the numbers 1through 24 screened directly above or below the
corresponding port. Status LEDs numbered 1through 24 are located in the LED bank on the left side
of the unit.
10/100/1000Base-T Gigabit Ethernet Interfaces
The NetVanta 1234 front panel contains four 10/100/1000Base-T Gigabit Ethernet interfaces (RJ-45).
These interfaces are arranged in two stacked pairs, with the numbers G1 through G4 screened directly
above or below the corresponding port. Status LEDs numbered G1 through G4 are located in the LED
bank on the left side of the unit.
SFP Slots
The NetVanta 1234 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.)
Connection directly to an external modem requires a cross-over cable.
