Ports

Table 15-33 describes ports provided by a C72 node.

Table 15-33  Description of ports

Port

Description

GE network port

Connects to GE switches. A C72 node provides four onboard GE network ports.

USB port

Connects to a mouse, a keyboard, or other USB devices.

Serial port

Extends functions of the operating system and third-party software.

10GE SFP+ Ethernet optical port

When OceanStor 9000 is networked using 10GE switches, each node is configured with 2-port INTEL 10GE network adapters, each of which provides two 10GE small form-factor pluggable plus (SFP+) Ethernet optical ports to connect to the 10GE switches.

Indicators

You can initially identify the current operating status of a C72 node by observing its indicators. Table 15-34 describes indicators on a C72 node.
