Positioning and bolting down for earthquakes

Positioning the media gateway
Each media gateway is normally positioned adjacent to the control hardware in the rack or another media
gateway.
1
If the media gateways are supplied with cable ductwork, space the media gateways on 32-inch
(81.3-centimeter) centers +-1/8 inch (0.3 centimeter). They must be level and must be square with
respect to each other.
2
If the media gateways are supplied with cable slack managers, place the media gateways far
enough from the connection field to lay down the 32-inch (81.3-centimeter) slack managers and
to provide a little extra room for the cables to access the cable slack managers.
3
If earthquake protection is required, see
page 92.
4
If earthquake protection is not required, level the media gateways and adjust and lock the media
gateway stabilizing bolts to keep it from moving.
5
At the bottom of the media gateway, install the hole plugs provided in the holes previously
occupied by the four carriage bolts.
Installing earthquake protection for the media gateway

Installing concrete floor mounting
1
Position the media gateway in the exact position it is to occupy when the installation is complete.
2
Insert a pencil or marker through the holes previously occupied by the carriage bolts (front and
rear) in the bottom of the media gateway and mark the floor directly beneath each hole.
3
Roll the media gateway out of the way and drill four 1/2-inch (1.27-centimeter) diameter holes
about 1.5 inch (3.8 centimeter) deep at the locations marked in Step 2.
4
Insert concrete floor anchors (STARR part number 3425) into the holes.
