Quick Start Guide
Step 3: Install PCIe Cards and or Blower
Step 1: Unpack the ExpressBox 3T-V3
The box contains the following items:
Magma ExpressBox 3T-V3
Fan Blower
US Power Cord
Carry Bag
Quick Start Guide
If your PCIe card runs hot or requires more than 20
Watts of power, we recommend use of the provided
Fan Blower in the x4 PCIe slot. Use caution if using all
three PCIe slots. Check for heat with only two cards first.
Step 4: Connect Power
Attach the power cord to the back of the Magma product and plug into a
power source.
Magma ExpressBox 3T-V3 does not have ON/OFF switch. The BLUE LED
on the front is an INDICATOR, not a power switch. To turn ON the expansion chassis, simply connect to a Thunderbolt 3 equipped computer.
Fan Speed and Noise Adjustment
Step 5: Connect to Computer
For low power or self-cooled cards you can reduce the
fan noise by moving the jumper found under the removable cooling fan at the front of the chassis to the slowest
speed setting. If the chassis gets hot during use, you
should increase the fan speed to provide more cooling.
Connect a Thunderbolt 3 cable to one of the ports on the back of the
Magma product to the Thunderbolt 3 port on your computer. You can use
the second Thunderbolt 3 port to connect to another
Thunderbolt 3 device or a mini DisplayPort device.
The Factory Default is setting 2 (medium). The slowest
speed is setting 4 and the fastest speed is setting F.
