HX Controller
The newer MiVoice Office 250 architecture, referred to as the HX Controller, is designed to offer
digital telephone support right out of the box, yet still provide adequate capacity for IP phones, trunks,
and single-line devices. The hardware is detailed throughout this section. For installation instructions,
see “Installing the HX Controller Base Server Chassis“ on page 139 .
Chassis Description
The HX Controller is the newer Base Server chassis that houses the main processing module and
the various station/trunk expansion modules. The 2U height chassis can be placed on a
desk/table/shelf, mounted on a wall, or mounted in a standard rack.
The physical dimensions of the HX Controller chassis are listed in Table 10 below.
Front Panel
The front of the HX Controller chassis (see Figure 1 below) provides the following:
• Display Panel: A two-row, 14-character per row liquid crystal display (LCD) panel to show
system status and command messages.
• Control Buttons: A five-button, command-and-control interface for interacting with the system
via the display. The control buttons allow you to scroll through menu items to set system param -
eters during system installation and to perform other system routines.
• USB Ports: One 2.0 type A connector (for database backup via a portable flash drive) and one
2.0 type B connector (for system online monitoring via a PC).
• Status Indicators: Three light-emitting diodes (LEDs) for indicating system status (as viewed
from the front, left-to-right):
• System Alarm (lit red if a system fault or failure is detected)
• File System/Storage Access (lit green when accessing flash memory)
• Power On (lit green when the chassis is receiving power; lit red if the chassis backplane is
not functional)
The following illustration shows the front of the HX Controller chassis.
