Cabling Multiple Units - Avaya g700 Installation And Upgrades

Cabling multiple units

Avaya G700 Media Gateways can be mounted in equipment stacks with routers, switches, or
other Media Gateways. These elements are all compatible and are installed similarly. Consult
Avaya P333T User Guide for installation and cabling information. To link multiple units, each
G700 Media Gateway must be equipped with an Avaya X330STK Stacking Module on the rear
panel. Then, each unit in the stack is linked to the one above it. Finally, the bottom unit is linked
to the top unit. Stacks should always be built from the bottom, and new units should be added at
the top. Up to 10 units can be stacked in this way.
When deciding where to position the unit, ensure that:
It is accessible and cables can be connected easily.
●
Cabling is away from sources of electrical noise such as radio transmitters, broadcast
●
amplifiers, power lines and fluorescent lighting fixtures.
Water or moisture cannot enter the case of the unit.
●
There is a free flow of air around the unit and the vents in the sides of the case are not
●
blocked.
The two ends of the Octaplane cables incorporate different connectors. Each connector can
only be connected to its matching interface.
The following cables are used to connect stacked units:
Short Octaplane cable (Avaya X330SC) - light, ivory-colored cable used to connect
●
adjacent units.
Long Octaplane and Extra-Long Octaplane cables (Avaya X330LC/X330L-LC) - light,
●
ivory-colored cable used to connect units from two different physical stacks or those
separated by more than 12 inches (30 cm).
Redundant and Long Redundant cables (Avaya X330RC/X330L-RC) - black cable used to
●
connect the top and bottom switches of a stack.
