The TMV Board’s Memory
The TMV Board’s Memory
There are different types of memory used on the TMV board. Each is
described briefly below.
Serial Flash : Stores the gateware for the Comm FPGA. The Comm FPGA
must start from the Serial Flash memory.
Parallel Flash : Stores the gateware for the MView FPGA. The MView
FPGA’s are started under control of the Comm FPGA and the NIOS Comm
software.
SD Card : Stores all Configuration files, fonts, and graphics.
Rear Panel storage : Stores all network information in the Rear panel, not
on the TMV Main board. For example:
• Facility LAN’s MAC address, IP Address, Gateway, and NetMask.
• Control LAN’s MAC address, IP Address, Gateway, and NetMask.
• TMV location within the Trinix frame.
• Router Control System’s Primary IP Address and Secondary IP
Address.
The way that the TMV board uses this memory makes replacing a board a
very easy task.
Replacing a TMV Board
The TMV board is hot swappable to provide quick and easy replacement
with minimal downtime.
Follow these steps to replace a TMV board:
1. Remove the non-performing board from the routing switcher’s output
slot.
2. Remove the SD card from the non-performing board.
3. Insert the SD card into the replacement board’s SD slot.
4. Place the new board into the routing switcher’s output slot and then
lock it into place.
Once a board has been replaced, very little user interaction is required. The
replacement board will be identified by the slot it occupies in the Trinix
frame. The Rear panel provides the Network information, MAC address, IP
address, and so forth. All configuration items are stored on the SD card.
