The VG 31-08 is intended for indoor use only. To ensure normal operation and longevity of your device, install it in an environment that meets the requirements below.
You must keep the temperature and humidity in the equipment room within a certain range. Long-term high humidity will lead to bad insulation or even electricity leakage, mechanical property change, and corrosion. However, too low relative humidity is likely to leave captive screws loose due to contraction of insulation washers and static electricity that threatens the CMOS circuit on the device. High temperature accelerates aging of insulation materials and lowers reliability and service life of your VG 31-08.
The following table lists temperature and humidity requirements for the VG 31-08.

Warning:
Properly connect the grounding cable before connecting other cables and shorten the grounding cable as much as possible to protect the VG 31-08 and the peer device against lightning strikes.
The AC input end of the VG 31-08 is connected to an AC noise filter whose neutral point is connected to the chassis directly, thus forming a protection ground (PGND). The PGND must be connected to earth ground properly to safely channel the faradic current and leakage current to the ground and to make the whole device less susceptible to electromagnetic interference (EMI). The lightning high voltage introduced from the exterior network is also channeled to the ground through the grounding cable.
The grounding screw of PGND is located on the rear panel. Connect this screw to earth ground using a grounding cable. The grounding resistance should not be greater than 5 ohm.
The VG 31-08 provides a console port, through which you can configure the device.
The console cable is an 8-core shielded cable. At one end of the cable is an RJ-45 connector that can be plugged to the console port of the VG 31-08; at the other end is a DB9 (female) connector, which can be plugged to the serial port of the console terminal.
The following figure illustrates a console cable:
Figure 3-3 Console cable assembly
When configuring the VG 31-08 through a console terminal, follow these steps to connect the console cable:
Step 1: Select a console terminal.
The console terminal can be either a standard ASCII terminal with an RS232 serial port or more commonly, a PC.
Step 2: Connect the cable.
Power down the console terminal, and then connect the RS232 serial port on the console terminal to the console port on the VG 31-08 through the console cable.
For a 100BASE-TX Ethernet interface, you can use a category-5 twisted pair cable, as shown in the following figure:
Figure 3-4 Ethernet cable assembly
Ethernet cables fall into two types: straight-through (standard) and crossover. Use a crossover cable if you are connecting the voice gateway to a PC or router; use a straight-through cable if you are connecting the device to a Hub or an Ethernet switch.
& Note:
When preparing network cables, use shielded cables preferentially for the sake of electromagnetic compatibility.
Caution:
Read the mark above the interface carefully to avoid misconnection.
Follow these steps to connect the Ethernet cable:
Step 1: Insert one end of the Ethernet cable to the Ethernet port of the VG 31-08 and connect the other end to a hub, an Ethernet switch, or a router.
Step 2: Check that the LINK LED on the front panel is ON. ON means the network cable is correctly connected.
The VG 31-08 can connect dual-tone multi-frequency (DTMF) phones through its eight telephone ports. You may simply connect the FXS ports of the VG 31-08 with the telephone through the telephone cable.
& Note:
You are recommended to set the telephone to DTMF mode, as the VG 31-08 does not support pulse dialing; otherwise, you cannot place calls with the telephone.
The cables used for connecting FXO ports are telephone cables with ferrite bead and RJ-11 connectors at both ends. You can simply connect the VG 31-08 to a PBX through the telephone cable.
The VG 31-08 uses a built-in power supply with these specifications:
Rated voltage: 100-240 VAC; 50/60 Hz
Max. voltage: 90-264 VAC; 47/63 Hz
You are recommended to use a 3-core single-phase power socket with neutral point. The neutral point of the socket must be grounded reliably. Normally, the neutral point of the power supply system in a building was buried in the ground during construction and cabling. Before you connect the AC power cord, make sure that the power supply system in the building has been well grounded.
Step 1: Connect one end of the power cord to the AC-input socket on the VG 31-08 and the other end to the AC power outlet.
Step 2: Power up the VG 31-08.
Step 4: Check that the PWR LED on the front panel is ON, which means the power connection is correct.
Caution:
Normally, the startup information is displayed on the terminal screen after you power on the VG 31-08. For more information, refer to section 4.1.3 “Startup Process”.
Each time before you power up the VG 31-08 during installation, verify that:
l Enough clearance has been reserved around the VG 31-08 for ventilation, and the tabletop/workbench is stable enough.
l Proper power supply is used.
l The grounding cable has been correctly connected.
l The VG 31-08 has been correctly connected to other devices, such as a console terminal.
Caution:
Installation verification is extremely important, because operations of the VG 31-08 depend on its stability, grounding, and power supply.
As shown in Figure 4-1, connect the RJ-45 connector of the console cable to the console port on the VG 31-08, and the DB9 connector to the serial port on the PC.

For more information on the configuration related to protocols and functions for the VG 31-08, refer to H3C VG Series Voice Gateways Operation Manual.
The VG series voice gateways provide the command line interface (CLI), which allows you to implement hierarchical protections against unauthorized users. In system view, all the commands are put into different groups for the convenience of management, each group being associated to a view. You can switch between the views by executing particular commands. In normal circumstances, you can only execute the commands appropriate to the view that you access. However, you are allowed to execute in any view some common commands, such as ping, display, and interface. The CLI offers a series of configuration commands for you to configure and manage your voice gateway. It allows you to:
l Configure the device locally through the console port.
l Telnet to configure the voice gateway locally or remotely, and then telnet to access and manage other devices.
l Assign different users with different levels (guest, operator, and administrator) to prevent unauthorized users. Only administrator users are allowed to configure and manage the voice gateway.
l Get on-line help whenever you enter ?.
l Refer to the prompts and help information presented in English.
l Test network connectivity quickly with network diagnostic tools, such as tracert and ping.
l Have detailed debugging information to troubleshoot your network.
l Enter the non-conflicting keyword instead of the whole command for searching, because the CLI supports command prompting. For example, you can simply enter dis to search for the display command.
VG series voice gateways provide Web-based configuration, which is more direct and more convenient to use for primary or common users, compared to command lines configuration. Web-based configuration supports:
l Parameters settings for basic system functions, like Ethernet interface, static routing, and so on.
l Parameter settings for basic voice features.
l User login authentication for security.
