Chassis grounding is provided through the power cable, which uses a standard grounding plug. The chassis is also equipped with two multi 4 x 0.7 screw terminals for chassis grounding. The accessory kit contains a crimp-type ground lug that attaches to the two screw terminals. For more information, refer to the "Installing the Ground Connection" section on page 3-11.
Port numbering conventions for the Cisco VG224 are as follows:
•An external compact flash card is numbered CF 0.
•10/100BASE-T ports are numbered 10/100BASE-T 0/0 and 10/100BASE-T 0/1 from right to left.
•FXS voice port numbering begins at 2/0 and extends to 2/7, 2/15, or 2/23, depending on the number of voice ports.

Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040
The operating system for the Cisco VG224 voice gateway is the Cisco IOS software that resides in flash memory.
You can use an ASCII terminal or a PC to configure a Cisco VG224 voice gateway. The configuration can be performed in several ways:
•Locally, with a direct connection through the console port
•Remotely, with a connection through the auxiliary port and a modem
•Through Telnet and TFTP
If your Cisco VG224 voice gateway was ordered with the Simple Network-Enabled Auto-Provision (SNAP) option, no onsite configuration is required. When the Cisco VG224 voice gateway is powered on and connected, the SNAP application downloads the applicable configuration files automatically.
When a Cisco VG224 voice gateway is first installed, use the procedure in Chapter 4, "Power-On Procedure," for the initial configuration. This sets the basic communication parameters. After the
Cisco VG224 voice gateway is operating and able to communicate, use the procedures in the Cisco VG224 Voice Gateway Software Configuration Guide to configure the specific services and functions, or to make changes to the existing configuration.
There are multiple methods for configuring a Cisco VG224 voice gateway:
•System configuration dialog
•Configuration mode—Cisco IOS software command-line interface (CLI)
•setup command facility—Remote configuration through a LAN
•SNMP-based application—CiscoView or HP OpenView
•HTTP-based configuration server—Provides access to the CLI from a web browser
