Cabling Multiple Media Gateways

You can mount and cable up to 4 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, and D from bottom to top.

When cabling the media gateways together, refer to the TDM Cable Installation Diagram included with the shipment.

Cabling 2 Media Gateways

  1. Remove the bottom panel from media gateway B.
  2. If not already removed, remove the fan assemblies from media gateways A and B.
  3. Remove the right TDM/LAN bus terminator from media gateway A, and install it at the left end of the TDM/LAN bus on media gateway B. See Shift TDM/LAN bus terminator from media gateway A to media gateway B.

WARNING: Make sure to install the TDM/LAN bus terminators with the arrow on the back pointing upward.

  1. Remove the nuts on the posts of the plates covering the bottom right TDM/LAN cable routing slot of media gateway B and the top right TDM/LAN cable routing slot of media gateway A. See TDM/LAN bus cable routing slot plate removal.
  2. Pull open the EMI Gasket, and pass the TDM/LAN bus cable through the routing slots in both media gateways. Push the free end of the EMI Gasket back in place. Make sure the open corner of the gasket faces the rear of the media gateway. Once installed, the top media gateway should rest on and compress the gasket. See TDM/LAN bus cable routed through the media gateway.
  3. Install the lower terminator of the TDM/LAN bus cable on right end of TDM/LAN bus in media gateway A.

WARNING: Make sure the arrows on the back of the cable terminators point upward.

  1. Install the upper terminator of the TDM/LAN bus cable on the right end of the TDM/LAN bus in media gateway B.
  2. Flip over the routing slot plates and reinstall both. Once the plates are reinstalled, the ends of the routing slots are covered.
  3. If finished, reinstall the fan assemblies and bottom panel. Otherwise continue cabling media gateway C.
