Galaxy Expand - Platform and Hardware Overview

The Galaxy Expand hardware platform is part of the E-MetroTel overall server portfolio. While it can function as a Call Server platform with a variety of Call Processor configuration options for standalone operation, it can also be configured in High Availability (HA) mode with an active/standby pair of call processors across two independent chassis units, as a Survivable Remote Gateway (SRG) system with a single processor, or even as a highly compact, large scale FXO, FXS, PRI, or Digital Station gateway with no Call Processors.

Galaxy Expand Chassis

The Galaxy Expand Is based on a multi-slot 19 inch wide x 7" high (4U) x 10.25" depth chassis.  There are a total of 11 slots to support a variety of Server and/or telephony interface cards.  In addition, there is a slot for the Switch Fabric card, which is used for in-chassis communication by all the other pluggable cards.  All other cards, including server and telephony interfaces cards are optional.

The chassis and corresponding slot numbers is shown below:

Galaxy Expand Power Supply Cards

The Galaxy Expand chassis is always equipped with two redundant hot-swappable power supplies.  Each power supply has its own power cable. E-MetroTel recommends connecting each of these power supply cables to 120V supplies on different breaker circuits to provide maximum protection against power interuption. These are always provided in the slots labeled PPS1 and PSS2.

Galaxy Expand Fan Tray

The Galaxy Expand chassis is equipped with a fan tray to provide maximum cooling capability when running under full load. The fan tray is located on the lower potion of the chassis where the E-MetroTel and Galaxy Expand branding is positioned. 

Galaxy Expand Server Card Options

The Galaxy Expand hardware portfolio includes two different Server cards for call processing and must be seated in slot 7a (2930 processor) or 7a and 7b (i5 processor).
