Setting the VG248 on a Shelf or Table
Before setting the VG248 on a desktop, shelf, or other flat, secure surface, adhere
the rubber feet included with the VG248. To attach them to the chassis, peel the
rubber feet from the adhesive strip and place them adhesive-side down onto the
round, recessed areas on the bottom of the chassis. Place the VG248 right-side up
on a flat, smooth, secure surface.
Connecting the VG248 to the Network
You must connect the VG248 to the other IP telephony systems in the network,
such as Cisco CallManager.
Review these sections before connecting the VG248:

Connecting to the Ethernet Port
Use the Ethernet port to connect the VG248 to the IP network to access
Cisco CallManager (see
Figure 3-4
). The VG248 supports half- or full-duplex
Ethernet operation.
Warning
To avoid electric shock, do not connect safety extra-low voltage
(SELV) circuits to telephone-network voltage (TNV) circuits. LAN
ports contain SELV circuits, and WAN ports contain TNV circuits.
Some LAN and WAN ports both use RJ-45 connectors. Use caution
when connecting cables.
