My System Hangs Beyond A Certain Number Of Add-In Cards; Rackmounting The Chassis - Magma EB7-X8G2 User Manual

Magma

My system hangs beyond a certain number of add-in cards

Any PCI or PCI Express expansion scheme requires the cooperation of the computer system's BIOS in order to operate
properly, regardless of the platform (PC/Laptop/Server) or operating system (MS Windows/MAC OS/LINUX etc.)
The BIOS hosts the first and the most fundamental code (firmware) that a computer executes upon boot-up. It is then
that each and every PCI/PCIe add-in card (be it located on the host system or on Magma's expansions chassis) is
allocated Input/output memory space for proper operation.
By installing multiple add-in cards in one chassis or chaining multiple Magma chasses (as discussed in: Appendix A),
we're requesting more and more resources from the BIOS and thus must make sure we pre-allocate them sufficiently.
It is therefore imperative that our computing platform allocates at least 32KB of I/O memory space to allow multiple add
in cards to operate properly. This setting may be editable or preset by your BIOS (or computer) vendor. If you're having
this problem it is recommended that you first update your system to the latest firmware provided by your vendor.
Instruction on how to do that (as well as making a backup of your current BIOS firmware) should be provided by your
computer vendor on their web site.
In case this property is editable, you computer vendor should also be able to tell you how to select at least 32KB using
their BIOS interface.

Rackmounting the Chassis

Locate a vacant 4U slot in your rack that is within the reach of the one-meter cable that came with your EB7-X8G2-RAS
Expansion System. Install the rails in the rack as shown below:
Measure the rack from front to back so you can confirm how long the rail must be to fit properly.
Next, assemble the Slide piece with the end bracket as shown and secure with 2 Panhead screws and locking nut.
Ensure the Phillips screw head is located on the "open" side of the Slide pieces as shown.
Tighten finger tight only to allow for minor adjustment during assembly.Depending on the depth of your rack you may
select either the long or the short end bracket.
