Cabling the G650 Media Gateways
After mounting the G650 Media Gateways in the rack, you must connect the TDM/LAN cables between
them. You must also connect CAT5 cables to the appropriate slots on the back of the media gateways.
You can mount and cable up to five media gateways in a rack. The media gateway on the bottom is
referred to as media gateway A. The others are referred to as media gateways B, C, D, and E from bottom
to top.
When cabling the media gateways together, see the G650 TDM/LAN Cable Installation diagram included
with the shipment.
