3 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

POST1: Started	running Fri Oct 8 13:39:25 GMT 2010
POST1: Test #1	- Running ceeturboramtest
POST1: Running	diagshow

POST1: Script PASSED with exit status of 0 Fri Oct 8 13:39:54 GMT 2010 took (0:0:29)

POST2: Started running Fri Oct 8 13:39:54 GMT 2010

POST2: Test #1 - Running ceeportloopbacktest (SERDES)

POST2: Test #1 - Running ceeportloopbacktest (BACKPLANE)

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 switch. LED patterns are described in “Interpreting LED activity,” next.

If one or more LEDs do not display a healthy state, verify that the LEDs are not set to beacon. Use the switch module CLI switchShow command or the browser-based GUI to verify the LED state.

2.Use the Blade Server Enclosure’s Chassis Management Controller (CMC) GUIto verify that the converged network switch is working correctly.

For details, refer to the Hardware Owner’s Manual for the Blade Server Enclosure.

3.Review the system log for errors.

Any errors detected during POST are written to the system log. Access this log through the Module’s CLI errShow command.
