Internal
4.3.14 PCIe Slots
Depending on the system configuration there are up to two PCIe slots in the RXi Box IPC-XP. In a RXM1x2 the
supported PCIe speed is 2.5GBit/s (Gen 1) and the link width is x4. In a RXx5 or RXx6 the supported PCIe speed
is 5.0GBit/s (Gen 2) and the link width is x1 in Slot 1 and x2 in Slot 2.
4.3.15 PCI Slots
Depending on the system configuration there are up to 4 PCI Slots. The PCI speed is 33MHz. The PCI width is
32bit. The signaling voltage is 3.3V. The slot is 5V type keyed thus signaling that these slots are 5V signal level
tolerant.
4.4 Additional devices
4.4.1 Temperature Sensor
Temperature sensors are integrated in the CPU module and on the carrier. The sensor on the carrier shows the
local ambient temperature within the RXi Box IPC-XP.
The sensors of the CPU and Carrier are programmed to take actions to protect the devices from over-heating.
The CPU temperature sensor has a catastrophic protection which shut down the CPU core voltage if the die
temperature reaches its final limits.
4.4.2 NVSRAM (Non-Volatile Random-Access Memory; not on RXM1x2)
The RXi Box IPC-XP contains a NVSRAM (mounted on the riser card) which is automatically backed up when the
PC is switched off or loses its power supply. It is not supplied with the battery power therefore an exhausted
Lithium coin will not cause any loss of data stored in that NVSRAM. For accessing the NVSRAM please ask our
support team.
