Accessing the converged network switch

Accessing the converged network switch

The converged network switch is managed as a single element. It has a single IP address and
appears as a separate entity to the Telnet protocol and the Simple Network Management Protocol
(SNMP).
When SNMP devices send SNMP messages to a management console running SAN management
software, the information is stored in a Management Information Base (MIB). The switch module
OS supports the FibreAlliance Fibre Channel Management (FCMGMT) MIBs, allowing the provision
of needed information to a SAN administrator.
Secure Telnet access is available using Secure Shell (SSH), a network security protocol for secure
remote login and other secure network services over an insecure network.
Browser-based GUI management is available through a secure browser using Secure Sockets Layer
(SSL). The SSL security protocol provides data encryption, server authentication, message integrity,
and optional client authentication for a TCP/IP connection. Because SSL is built into all major
browsers and Web servers, installing a digital certificate enables the SSL capabilities.

Interpreting POST results

The power-on self test (POST) system check is performed each time the converged network switch
is powered on, rebooted, or reset.
Example POST Output
During POST, the LEDs are activated in various indicator patterns.
Perform the following steps to determine POST completion status.
1. Verify that the LEDs on the converged network switch indicate a healthy converged network
2. Use the Blade Server Enclosure's Chassis Management Controller (CMC) GUIto verify that the
3. Review the system log for errors.
