resistance in the ground cords. To provide proper ground, wear the strap snug against
the skin.
-
Use heel straps, toe straps or boot straps at standing workstations. Wear the straps on
both feet when standing on conductive floors or dissipating floor mats.
-
Use conductive field service tools.
-
Use a portable field service kit with a folding static-dissipating work mat.
Installation
Ensure that all power is removed from the VPX backplane before inserting the module. Prior to
inserting the VP1-250-eSSD into the card cage, it is necessary to verify the slot the module will
be inserted into is compatible with the module. VPX modules are typically keyed to prevent the
insertion of a module into the wrong card cage slot. The VP1-250-eSSD utilizes two guide
modules with keying. In the standard configuration both guide modules are not keyed. Caution
must be used to ensure the module is not inserted into a slot that will cause damage to the
module, the backplane, or any other device attached to the system. Guide module keying is
available with no key, 0°, 45°, 90°, 270°, and 315°.
Considerations for airflow provided to the module are important. Ensure that proper airflow is
provided to air-cooled modules. Conduction cooled modules should only be used in a properly
configured conduction cooled card cage. Operation of a conduction cooled VPX module in an air
cooled environment can result in overheating of the storage device.
The use of an NMVe device in a VPX environment requires the REF_CLK frequency be set to
100MHz. This is typically set in the BIOS of the VPX computer the NVMe module is attached to.
Option Configuration
Safety Ground, Jumpers JP1 & JP2:
By installing jumpers at locations JP1 and JP2 the ground plane of the VPX module will be
connected to the VPX key guides. This allows for the option of connecting the VPX module
ground plane directly to the VPX chassis ground plane.
