G860 Media Gateway
Issue 5.1 June 2006 149
The SC board is designed according to PICMG CompactPCI standards for high-availability
systems. It supports hot-swap operation, system management, and environmental monitoring.
The SC board has two PCI Mezzanine Connectors (PMCs). One is occupied by the SC board
with on-board hard disk and the second is reserved for future expansion of board functionality.
The two 10/100 Base-TX redundant Ethernet ports connect the SC board with the two Ethernet
Switch boards via cPSB dedicated links in the midplane. The front panel PS2 COM serial port
provides RS-232 console connection. The RS-232 console connection can be made via the SC
front panel PS2 Com serial port or via the RS-232 serial port on the SA/RTM.
The SC board is accompanied by a Synchronization and Alarm (SA) Rear Transition Module
(RTM) board. The SA board is inserted into the midplane directly behind the main SC board and
contains an RS-232 port for connecting to a console terminal.
Cooling system
G860 media gateway components are cooled by a fan tray unit (FM/5K), located at the left of
the card cage. An auxiliary fan tray unit (FMR/5K) is located in the top right-hand corner of the
chassis, above the power supply units.
LEDs
The FM/5K fan tray unit panel contains the system’s alarm indicators (LEDs) Alarm Cutoff and
Reset Buttons.
The alarm indicators are connected to the fault detection and alarm system provided with the
G860. As needed, LEDs indicate critical, major or minor system faults as well as system and
shelf alarms.
