Galaxy Express - Platform and Hardware Overview

The Galaxy Express is a hardware platform that is part of the E-MetroTel overall Galaxy portfolio.  Galaxy Express is built around adaptability and flexibility for your branch office locations. As your offices grow the need for easy expansion that doesn't interrupt your business is important. Galaxy Express is designed for just this purpose. 

Galaxy Express is a dual slot expansion module that allows for the expansion and addition of Digital Stations, Analog Stations, and PRI trunking.

Galaxy Express Chassis

The Galaxy Express Is a small, standalone desktop or wall mounted chassis measuring 7.9375 x 5.875 x 1.75 inches (LxWxH) or 202 x 149 x 44 cm.

There are a total of 2 slots to support interface cards that can provide flexible telephony interfaces to UCx software running on any of the E-MetroTel supported server platforms.  The telephony cards operate independently of each other and can communicate with a common UCx server, or, even different UCx servers. Note that the two card slots are connected internally via a switch fabric to Eth2, so a only single Ethernet connection to the customer network or UCX using Eth2 should be used. 

Wall Mounting Holes

The following diagram depicts the spacing of the holes when using the mounting wing hardware (included in the packaging) for wall mounting. If printed from this web page it will not necessarily be recreated at proper scale, so it is for layout informational purposes only.

Note that the mounting brackets must be connected as depicted in the above diagram as the spacing of the holes differs between the two sides of the bracket.  The long flat side of the bracket will face the mounting wall while the side of the bracket with two distinct ears attaches to the holes in the sides of the Galaxy Express chassis.
