3.5 Main X-point modules
– XC-M256128-3GHD
The XC-M256128-3GHD is the main X-point card in the VikinX Modular 256x256 router
frame.
A maximum of two XC-M256128-3GHD cards can be inserted into the 21RU frame, providing
control of signals between each 32x32 X-point module. An FR-256256-MR-3GHD equipped
with 8x 32x32 X-point modules and 2x XC-M256128-3GHD modules builds a 256x256
router; with only 1x XC-M256128-3GHD module inside, the router size becomes 256x128.
Note that it is not possible to build a 128x256 router; only 256x128 or 256x256.
If there are no XC-M256128-3GHD cards in the frame, or the present XC-M256128-3GHD
cards are not working, the user has still the ability to control each of the XC-3GHD-M3232
5
cards in the frame as independent 32x32 routers. This feature is useful when configuring the
router, considering protection of important I/O combinations by configuring them to the same
32x32 I/O part of the VikinX Modular 256x256 router frame.

3.5.1 Card insertion
To insert an XC-M256128-3GHD card, slide the module along the plastic guide rails into its
position. On both sides of the card tray there is a hole next to each module slot. Use the two
handles, which are located on the front of the module to seat the module.
5 Note that XC-3GHD-M3232(-B) in this chapter also applies to XC-SD-M3232.
