Configuring the Magma PE6R4
6-Slot Expansion Chassis
Connecting the Expansion Chassis
To install the PCIe host card in the computer:
1 Turn off the expansion chassis, your com-
puter, and any peripherals. To ensure proper
grounding, connect the expansion chassis to a
power source (such as a power strip or wall out-
let), using the supplied AC cable.
2 Open the computer case. For additional de-
tails on installing a card in your computer, refer
to its documentation.
3 Install the host card in the lowest numbered
PCIe slot in your computer. On a Windows PC,
this will be the slot farthest from the graphics
card. On a Mac, this will be the slot closest to the
graphics card.
Connect the host card to the chassis:
1 Attach one end of each Infiniband cable to the
two connectors (labeled x1 and x3) on the host
card.
2 Attach the other end of each cable to the cor-
responding connector on the expansion chassis.
Each cable should be attached to connectors
with the same label (x1 or x3) on both ends.
3 If using a SCSI HBA, do one of the following:
• On Windows computers, install the SCSI
HBA in the 64-bit slot closest to the graph-
ics card.
– or –
• On Mac computers, install the SCSI HBA
card in the highest numbered remaining
slot.
Installing the Digidesign Cards
To install Digidesign audio cards in the chassis:
1 Install the Pro Tools|HD Core card in the first
slot of the expansion chassis.
2 Install the remaining cards in successive PCI
card slots in the chassis, in the following order:
•HDAccel
•HDProcess
3 Connect all Pro Tools cards with TDM FlexCa-
bles. See “Connecting Pro Tools|HD Cards” on
page 6.
Before removing cards from their antistatic
bags or handling any card, discharge any
static electricity that may be on your clothes
or body by touching a grounded metal sur-
face (such as the power supply case inside
your computer).
Refer to your computer’s documentation to
verify slot order.
Refer to the expansion chassis guide for
detailed instructions on connecting the
Infiniband cables.
Only Pro Tools|HD (for PCI) cards can be
installed in the chassis. PCIe cards are not
supported.
