ATTENTION

In the MIB file we provide the CPU voltage and temperature information. The voltage value varies on different

CPUs. The reference values list in below.

V_CPU: The value is dependent on the CPU.

V_GFX: The value is dependent on the CPU.

VTT_CPU: 1.06V

VCCSA_CPU: 0.9V

V1.05: 1.05V

V5.0: 4.99V

The temperature value varies on different CPUs. The reference values list in below.

CPU: In high temperature: actual=80..2∘C，display=84∘C，In regular: actual=54∘C，display=44.8∘C

System: In high temperature: actual=81..5∘C，display=82∘C，In regular: actual=48∘C，display=46.6

OpenVPN

OpenVPN provides two types of tunnels for users to implement VPNS: Routed IP Tunnels and Bridged

Ethernet Tunnels.

An Ethernet bridge is used to connect different Ethernet networks together. The Ethernets are bundled into one

bigger, “logical” Ethernet. Each Ethernet corresponds to one physical interface (or port) that is connected to

the bridge.

On each OpenVPN machine, you should carry out configurations in the /etc/openvpn directory, where script

files and key files reside. Once established, all operations will be performed in that directory.

Ethernet Bridging for Private Networks on Different Subnets

1. Set up four machines, as shown in the following diagram.

Host A represents the machine that belongs to OpenVPN A, and Host B represents the machine that belongs

to OpenVPN B. The two remote subnets are configured for a different range of IP addresses. When this

configuration is moved to a public network, the external interfaces of the OpenVPN machines should be

configured for static IPs, or connected to another device (such as a firewall or DSL box) first.
