MAGMA
Chapter 2 Hardware Installation 5
If you are installing a 64-bit 7 slot expansion chassis, two expansion
cables are required to achieve the full 64-bit bandwidth. Make sure you
connect the cable properly by mating teal to teal and purple to purple.
The 64-bit system will work with only one cable installed using the teal
connectors, but the system will only function at 32-bit speed when only
one cable is used.
Secure the cable with the captive thumbscrews. It is important that the
cable be attached securely to the connectors at both ends.
Before connecting the power cord, check that the expansion chassis
On/Off switch is set to the OFF position. This switch is located on the
left side of the chassis.
NOTE
If at all possible, plug all power cords from the Magma expansion
chassis and your host computer into a shared power strip,
preferably one that has surge and noise suppression circuitry built
into it.
Recheck the Installation
Check your installation before powering up the Magma expansion
chassis for the first time. Although the power supply has an over voltage
protection device built into it, it may not "trip" in time to fully protect a
device that has been improperly connected, or whose power cable has
been damaged.
