Functional Description
ATCA-8310 Installation and Use (6806800M72E) 81
The SMBus interface of the Ibex-Peak is connected to onboard devices like Clock PLL's,
Temperatures sensors and the SPD PROM's. The BIOS reads memory configuration parameters
from SPD PROM.
4.3.2.8 Ibex-Peak RTC
The integrated RTC requires a 32kHz quartz and a backup battery. There is one battery that
provides backup for the GPP-RTC as well as the SPP-RTC. A CR2030 battery is used to provide
backup.
4.3.3 GPP Ethernet Connectivity
Two Ethernet connections are provided from the GPP to the switch. For other purposes, one
Ethernet interface is available on the front panel.
