Using the Fabric Access interface to the Fabric OS, a client application can retrieve information and modify the configuration of Brocade switches in the fabric. 20 4424 Blade Server SAN I/O Module Hardware Reference Manual 53-0000571-01 Interpreting POST results 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. Brocade Web Tools 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 SAN I/O Module is powered on, rebooted, or reset. Example POST Output POST1: Started running Tue Nov 9 20:27:57 GMT 2004 POST1: Test #1 - Running turboramtest POST1: Test #2 - Running centralmemorytest POST1: Test #3 - Running cmitest POST2: Running diagshow POST1: Script PASSED with exit status of 0 Tue Nov 9 20:28:10 GMT 2004 took (0: 0:13) POST2: Started running Tue Nov 9 20:28:12 GMT 2004 POST2: Test #1 - Running camtest POST2: Test #2 - Running txdpath POST2: Test #3 - Running spinsilk (SERDES) POST2: Running diagshow POST2: Script PASSED with exit status of 0 Tue Nov 9 20:29:11 GMT 2006 took (0: 0:59) Initializing Ports .... Port Initialization Completed Enabling switch... 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 SAN I/O Module indicate a healthy SAN I/O Module. 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 SAN I/O Module CLI switchShow command or Web Tools to verify the LED state. For information about how to turn beaconing on and off, see the Fabric OS Administrator’s Guide or the Web Tools Administrator’s Guide. 2. Use the Blade Server Enclosure's Chassis Management Controller (CMC) GUI to verify that the SAN I/O Module 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. For information about this command, see the Fabric OS Command Reference Manual. For information about error messages, see the Fabric OS System Error Message Reference Manual. 4424 Blade Server SAN I/O Module Hardware Reference Manual 53-0000571-01 21 3 Interpreting LED activity Interpreting LED activity Each SAN I/O Module uses LEDs to indicate status. These LEDs are shown in Figure 5. FIGURE 5 LED Locations TABLE 4 Key to Figure 5 Location Indicator Color Operation 1 FC (external) port status green/amber Note: LED meanings are not valid during boot, diagnostics, or POST. Green: Off (dark): No signal carrier or unlicensed. Steady: Online normal active port but no port activity. Flickering: normal active port (I/O activity). Slow blink: Online but segmented. Fast blink: Internal loopback. Amber Steady: Signal present but not online. Slow blink or flash: Disabled port (less than two second interval). Fast (rapid) blink or flash: Error or fault with port (less than 1/2 second interval). 2 FC port x speed green/amber Amber on: 4 Gbit/sec FC Green on: 2 Gbit/sec FC Both off (dark): 1 Gbit/sec FC 3 (status icon) and 4 (LED) module status green/amber Off: SAN I/O Module is off or power supplies for the Blade Server or onboard DCC have failed. Green: No errors and all ports are ready for use. Amber: Steady: Boot-up state, port(s) offline, or in reset state. Blinking (green/amber): One or more environmental ranges are exceeded, or error log contains diagnostic error messages. Note: The LED might blink during testing. 22 4424 Blade Server SAN I/O Module Hardware Reference Manual 53-0000571-01 Removing and replacing the SAN I/O Module 3 TABLE 4 Key to Figure 5 (Continued) Location Indicator Color (Continued) Operation (Continued) 5 (LED) and 6 (icon) module power green Off: SAN I/O Module is off or power supplies for the Blade Server Enclosure or onboard DCC have failed.
