Chapter 6  Switch Monitoring and Maintenance

6.1  Monitoring the Switch

Although the S9500 series have undergone a comprehensive and strict factory test before delivery, there might be some fault occurring due to improper installation. This chapter describes how to troubleshoot the S9500 series.

6.1.1  Troubleshooting Console Terminal

If the system is normal after the Switch is powered on, the booting information will be displayed on the Console terminal. If the configuration system has failed, the Console terminal may give illegible output or nothing at all.

1)         The terminal gives no displays after the Switch is powered on.

In this case, you should check if:

l           The power system is working normally.

l           The SRPU is working normally.

l           The Console cable has been connected to the Console port on the SRPU.

If no problem has been found in the above checking, the symptom is very likely caused by the errors listed below.

l           The Console cable is not connected to the right serial port, that is, the port in use is not the one configured on the terminal.

l           There are Console terminal parameter errors. (According to the parameter setting requirements, you should set the baud rate to 9600, data bits to 8, parity to None, stop bits to 1, flow control to None, and select VT100 as terminal emulation.)

l           The Console cable is not in good condition.

2)         The terminal gives illegible characters.

This symptom is very likely caused by a Console terminal setting error. In this case, check that you have set the baud rate to 9600, data bits to 8, parity to None, stop bits to 1, flow control to None, and select VT100 as terminal emulation.

6.1.2  Troubleshooting PSU

Table 6-1 Description of the LEDs on PSU

LED	Description
INPUT	It keeps ON if the power input is normal and the PSU switch is at ON position. It keeps OFF if the power input has failed or if there is no power input at all.
OUTPUT	It keeps ON if the power output is normal and OFF in any other cases.
FAIL	It keeps ON if the PSU has failed and OFF in any other cases.

 

Following are the PSU faults that likely appear and the methods used for problem isolation.

l           The Input LED (green) and Output LED (green) stay ON, but the display power command shows that the PSU is not in position (but the other PSU operates normally). Such a problem is likely caused because of the poor contact between the PSU and the backplane due to a badly seated PSU. In this case, switch off the power supply, loosen the captive screws on the PSU, push the PSU into the chassis a little bit, tighten the captive screws, and switch on the power supply to check that the normal state is resumed.

l           The Input LED (green) and Output LED (green) are OFF. In this case, check that the power cords are connected correctly, the power cords are in good condition, and the power switch has been put in the ON position.

l           The Fail LED (red) is ON. In this case, check that the correct power voltage is in use (i.e., 90 to 264VAC, 50-60 Hz for AC PSU, and -36V to -72VDC for DC PSU).

l           The Fail LED (red) is ON. In this case, check that the air filter protecting the fan tray is clean. Excessive dust accumulated on the air filter will block the fan tray from free ventilation and even lead to power supply failure.

l           If you cannot solve the problem yet after going through the above checking steps, contact H3C technical support engineers rather than disassembling the PSU yourself.

6.1.3  Troubleshooting Fan Tray

The S9500 series provide two LEDs on the fan tray. You can read them and know if the fan tray is OK.

Table 6-2 Description of fan tray LEDs

Indicator	State description
RUN	Green indicates that the fan tray is normally operating. OFF indicates that the fan tray has failed.
ALM	Red indicates that the fan tray has failed. OFF indicates that the fan tray is in normal state. &  Note: Once powered on, the fan LED ALM will be on for two to three seconds.

 

If the RUN LED is OFF, check if:

l           The fan tray has been well seated.

l           All the cables connecting the fan tray and the backplane have been correctly connected and are in good condition.

l           The fans are working normally.

l           The rotation of the fans has not been blocked.

6.1.4  Troubleshooting LPU Boards

The S9500 series provide LPUX LEDs on the SRPU for the user to observe the state of these LPUs.

Table 6-3 Description of LPU LEDs

Indicator	State description
RUN	ON indicates LPU failure. OFF indicates that the LPU has failed or it is not in position at all. Normal blinking (1-second ON and 1-second OFF) indicates that the board is operating normally. Fast blinking (125-ms ON and 125-ms OFF). The RUN LED is on or blinking when the board starts up. If the RUN LEDkeeps blinking fast, it indicates that board registration fails.
ALM	OFF indicates that there is no LPU alarm or the LPU is not in position at all. ON indicates that there is LPU alarm.
2~6 (S9505) 0~3, 6~9 (S9508) 0~5, 8~13 (S9512)	On S9505, LPU 0 through LPU 4 respectively correspond to slots 2 through 6. On S9508, LPU 0 through LPU 7 respectively correspond to slots 0 through 3 and 6 through 9. On S9512, LPU 0 through LPU 11 respectively correspond to Slots 0 through 5 and 8 through 13.

II. Upgrading software through console port (XModem)

1)         Brief introduction to XModem

XModem, a type of file transfer protocol, is broadly applied for its simplicity and good performance. It transmits files through serial interfaces, supporting 128 bytes and 1Kbytes in terms of data unit, checksum and CRC in terms of checking mode, and multiple retransmissions (usually ten attempts) in the event that packet errors are found.

XModem completes transmission by the receiving program (receiver) and the sending program (sender). In XModem, the transmission begins with the sending of negotiation characters from the receiver for the purpose of check mode negotiation. After passing the negotiation, the sender is allowed to send the first data packet. Upon the receipt of the complete packet, the receiver checks the packet using the agreed checking mode and will send an ACK if the packet has passed the check and a NAK if not. Receiving the ACK, the sender will send the next packet; receiving the NAK instead, the sender will retransmit the previously sent packet.

III. Upgrading software through management Ethernet port (TFTP)

1)         Introduction to TFTP

Trivial file transfer protocol (TFTP) is well suited to the file transfer between a server and a client that do not need complex interaction.

In TFTP, the transmission is initiated by the client. When downloading a file, the client sends a read request packet to the TFTP server, receives the data packets from the server, and sends the ACK to the server. When uploading a file, the client sends a write request packet to the TFTP server, then sends the data packets to the server, and receives the ACK from the server. The TFTP transmission files have two forms, i.e., binary for program transmission and ASCII for text transmission.

Following is the upgrading procedure described taking the S9512 working as a TFTP Client as an example.

2)         TFTP upgrade procedure

Step 1: Connect the Switch to a PC where the desired file is located via the management/upgrade Ethernet port. (In this case, you should know the IP address of the PC. At the same time, connect the Switch to an external PC (that can be the same one that contains the desired file) via the Console port.

Step 2: Run the TFTP Server program on the PC connected to the management/upgrade Ethernet port, and specify the path for upgrading the application files.

Step 3: Run the terminal emulation program on the PC connected to the Console port, and boot the switch to access the Boot menu.

Step 4: Enter 5 in the Boot menu. Press <Enter> and the system will access the download application program menu.

IV. Upgrading software through management Ethernet port (FTP)

1)         Introduction to FTP

The S9500 series applications can also be updated through the Ethernet port and using FTP.

Following is the upgrading procedure, using the S9512 working as an FTP Client as an example.

2)         Upgrade procedure

Step 1: Connect the Switch to the PC containing the desired file via the management/upgrade Ethernet port. (In this case, you should know the IP address of the PC. At the same time, connect the Switch to an external PC (that can be the same one that contains the desired file) via the Console port.

Step 2: Run FTP Server on the PC connected to the management/upgrade Ethernet port, specify the path of the upgrading file, and set the login username and password.

Step 3: Run the terminal emulation program on the PC connected to the Console port, and boot the Switch to access the Boot menu.

Steps 4 ~ 8: See the corresponding steps in the upgrading procedure via TFTP for reference.

 

 

After downloading the host program through the Boot menu, you must specify it as the next boot program. In the following example, the host program is 9500.app.

MAIN  MENU

 

    1. Boot with default mode

    2. Boot from Flash

    3. Boot from CF card

    4. Enter serial submenu

    5. Enter ethernet submenu

    6. Modify Flash description area

    7. Modify bootrom password

    0. Reboot

 

Enter your choice(0-7):      

Enter your choice(0-7): 6

Please input '0' or '1' ('0':Boot from Flash, '1':Boot from CF card)

BootDev = 0

 

FlashFileName = 9500.app

6.3.3  Local or Remote Loading through CLI

If your terminal is connected to the switch over a network, you can load Boot ROM and host program at the remote through CLI.

I. Loading using FTP

Run FTP server on a local PC, provided you have configured username and password and have set the correct file directory. Suppose IP address of the PC is 10.10.110.1. Log on to the switch using Telnet or through the Console port to send host program to the switch using FTP.

Suppose that the main boot file is SWITCH002.app; the active host program is SWITCH001.app; the Boot ROM program is SWITCHbtm.btm. You can follow these steps after logging on to the switch.

Step 1: Download the software to the switch using FTP.

<H3C> ftp 10.10.110.1

Trying ...                                                              

Press CTRL+K to abort                                                 

Connected.                                                               

220 WFTPD 2.0 service (by Texas Imperial Software) ready for new user

User(none):9500                                                          

331 Give me your password, please                                   

Password:                                                                

230 Logged in successfully      

[ftp] get SWITCH002.app SWITCH002.app

[ftp] get Switchbtm.btm Switchbtm.btm

[ftp] bye

 

 

Step 2: Specify the next boot program. If the switch has two SRPUs, specify the load programs respectively for the active and standby SRPUs. Suppose the current standby SRPU is at slot 7.

l           Load Boot ROM program

<H3C> boot bootrom flash:/Switchbtm.btm slot 6

<H3C> boot bootrom slot7#flash:/Switchbtm.btm slot 7

l           Load host program

<H3C> boot boot-loader flash:/SWITCH002.app

<H3C>boot boot-loader slot7#flash:/SWITCH002.app

 

 

<H3C> display boot-loader

The app to boot of board 6 at the next time is: flash:/SWITCH002.app

The app to boot of board 6 at this time is: flash:/SWITCH002.app

The app to boot of board 7 at the next time is: flash:/SWITCH002.app

The app to boot of board 7 at this time is: flash:/SWITCH002.app

<H3C> reboot

 

 

Boot ROM and host program loading is completed now.

II. Remote and local loading using TFTP

Using TFTP is similar to using FTP in remote and local loading via commands. The only difference is that you use the tftp get command to download software to the switch. In this case, the switch can only be used as a TFTP client to download the software to its Flash memory from the TFTP server. The remaining steps after downloading are the same as those of remote loading using FTP.

6.3.4  Service Processor Card Program Upgrade

The S9500 series only provide a Flash memory of 16M, but the host program (including L3PLUS) is over 15M. If no CF card is inserted, therefore, the Flash memory is insufficient for the loaded files. You must use the update l3plus command to download the host program (the APP file) with L3PLUS program included to the SDRAM memory and then complete upgrade. For details about this command, refer to H3C S9500 Series Routing Switches  Command Manual.

 

 

6.3.5  Troubleshooting Software Upgrade

These types of problems may occur during software upgrade:

I. No response from SRPU serial interface

Check if the serial interface cable is in good condition and if its attributes are set correctly.

II. Uploading configuration file or host program using FTP fails

Please check

l           If the configuration is correct and if the FTP server is started.

l           If the Flash has enough space for the target files.

l           If the TFTP flag is selected (TFTP is not supported).

III. No configuration saving during LPU reboot

Before saving the configuration, you must check the operating status of the LPU. Do not save the configuration during the LPU reboot. Otherwise, the configuration you want to save may be lost.

IV. LPU program loading fails or you cannot register for a long period

l           Check LPU type to see if this type is supported on the current host program.

l           Check if the LPU Boot ROM program matches the host program before upgrade.

l           Check if LPUs are well seated.

l           Insert an LPU to different slots to check if it is OK.

l           Check if the host program exists and if the current host program is the running one.

V. Insufficient Flash memory

l           Empty the recycle bin when the LPU starts.

l           Delete the unused files in the Flash.

6.4  Password Loss

If the Super password or Boot ROM password of the Switch is lost, please contact the local agent.
