3.11 Gigabit Ethernet
The VPX6600 uses the Intel i350 Quad Gigabit Ethernet Controller, which
contains both the media access control (MAC) and the physical layer (PHY) for
each port.
The VPX6600 provides three Gigabit Ethernet ports configured as follows:
•
Two 1000BASE-BX ports connected to the P1 VPX backplane
connector to be used on the board-to-board Control Plane interface
as specified in VITA 65 OpenVPX specification.
•
One 1000BASE-T fully-integrated port available on the P2 VPX
backplane connector to be used as a standard Ethernet connection.
3.11.1 Configuring PXE Boot
For information regarding how to boot from the network, refer to
Aptio
Skylake Core BIOS Manual.
3.12 Real Time Clock (RTC)
A Motorola
®
MS146818B‐compatible real‐time clock (RTC) is included in the
Intel® CM236 PCH
. The RTC has 256 bytes of battery‐backed RAM and runs
on a 32.768 KHz crystal with a 3V battery. The RTC performs two key
functions:
•
It keeps track of the time of day, and
•
It stores system data, even after powering down the system.
Note:
After the RTC battery is removed from the board with it otherwise
unpowered, the last BIOS settings will be retained for approximately 80
minutes by an onboard supercap. After that, the settings will be lost unless
the module is reconnected to the RTC battery or connected to VCC_3.3VSBY.
Note:
If the supercap has drained and the RTC voltage drops below 2.5V, or
when a BIOS update has been done, the first time the system is powered on it
may partially boot and then restart up to two times. This behavior is normal.
3.13 Security
3.13.1 Trusted Platform Support
The VPX6600 uses the Atmel AT97SC3204 fully integrated security module,
which implements version 1.2 of the Trusted Computing Group (TCG)
specification for Trusted Platform Modules (TPM). The TPM includes a
cryptographic accelerator capable of computing a 2048-bit RSA signature in
200ms and a 1024-bit RSA signature in 40ms. Performance of the SHA-1
accelerator is 20μs per 64
-byte block.
