2. PHYSICAL DESCRIPTIONS
NetVanta 1230 Series
The NetVanta 1230 and NetVanta 1230P 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 two 100/1000Base-T Gigabit Ethernet interfaces
all accessed via standard RJ-45 connectors. Four 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-232CONSOLE port (DB-9)
located on either the rear panel, Telnet session, or Web-based graphical user interface (GUI). The NetVanta
1230 is RoHS compliant.
Power over Ethernet
The NetVanta 1230P Series provides the same basic functionality as the NetVanta 1230 Series products. PoE
provides the ability to detect attached powered devices (PDs), and deliver power to the PD via existing CAT 5
cabling. The NetVanta 1230 Series is fully compliant with the IEEE 802.3af PoE standard. By default, the PoE
switches discover and provide power to IEEE-compliant PDs. NetVanta 1230P Series PoE supports legacy PoE.
SFP Module Slots
The NetVanta 1230 Series devices support four SFP slots that accept a number of industry standard SFP
modules for high-speed uplinks or switch stacking. SFP slots G1 and G2 provide up to 1 Gbps and SPF slots G3
and G4 provide up to 2.5 Gbps fiber connectivity. For a list of supported SFP modules, visit the ADTRAN
website at http://www.adtran.com.
NetVanta 1230 Series Shipping Contents
Each NetVanta 1230 unit is shipped in its own cardboard shipping carton. Open each carton carefully, and avoid
deep penetration into the carton with sharp objects.
After unpacking the unit, inspect it for possible shipping damage. If the equipment has been damaged in transit,
immediately file a claim with the carrier and contact ADTRAN Customer Service (refer to the Support page on
the ADTRAN website at http://www.adtran.com/support).
Domestic shipments of the NetVanta 1230 Series include the following items:
• NetVanta 1230 Series base unit
• Quick start guide
• Rackmount brackets and screws
• A detachable power cable with a grounded, three-prong plug

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.
