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:

These are always provided in the slots labeled PPS1 and PSS2.
