GSC Mezzanine Cards
Preliminary Requirements
Perform the following steps before installing an HCRX board on your
Model 744:
1 If the Model 744 is already installed in your system chassis, you must re-
move it. See Chapter 3 of this book for instructions on removing and re-
placing the Model 744.
2 Place the Model 744 on a static-free mat on a clean, level surface.
NOTE: There is one GSC connector on the left side of an HCRX board. A GSC card
is installed in an HCRX board in the same manner as on the expansion
adapter. See “GSC Mezzanine Cards,” earlier in this chapter.
