l Ensure that the Boot ROM version matches the host software version when you load the Boot ROM and host software. You are recommended to load the Boot ROM program only when the host software to be loaded does not match the existing Boot ROM version. Frequent loading is discouraged.

l The Boot Menu can only be used to load the Boot ROM program and host software of SRPUs. To load the Boot ROM program of LPUs, use command lines.

7.2 Loading Software Locally through Boot Menu

If your terminal is directly connected to the switch, you can load Boot ROM and host software locally.

Before loading the software, make sure that your terminal is correctly connected to the switch.

& Note:

The steps that you should take to load Boot ROM program are the same as those you take to load host software, except that in a Boot ROM program loading process you need to press <Ctrl+U> and <Enter> after accessing the Boot ROM menu and will view a different prompt message. Boot ROM loading steps are described below as an example.

7.2.2 Loading Software from Console Port Using Xmodem

I. Introduction to XModem

The XModem protocol is a file transfer protocol widely used due to its simplicity and good performances. XModem transfers files through the console port, supporting data packets of 128 bytes and 1KB. With respect to reliability, it supports checksum, CRC, and error packet retransmission mechanism. Normally, the maximum number of retransmission attempts is 10.

XModem transmission is completed by the receiving program and sending program. The receiving program initiates packet checking method negotiation by sending the negotiation character. If the negotiation passes, the sending program starts packet transmission. Upon the receipt of a complete packet, the receiving program checks it using the agreed-upon checking method. If the check succeeds, the receiving program sends an acknowledgement character; if the check fails, it sends a reject character. Upon the receipt of the acknowledgement, the sending program continues to send the next packet; upon the receipt of the reject, it retransmits the packet.

The subsequent steps are the same as those for loading Boot ROM, except for the messages displayed.

7.3 Loading Software Remotely or Locally through Command Lines

If your terminal is connected to the switch through a network, you can load Boot ROM and host software remotely through command lines.

7.3.1 Loading by FTP

Run the FTP Server on the local PC. Ensure that you have configured the username and password and set the correct file directory. Assume that the IP address of the PC is 10.10.110.1.

& Note:

l The S7502 supports dual image booting, that is, usually the switch boots with the main image (i.e. the primary file), but uses the backup image (i.e. the backup file) instead when the primary one has any error. Refer to section 7.4 “Booting the Switch with Dual Images” on page 7-14 for details.

l The S7502 also supports the upgrade by using a combined Boot ROM file, that is, upgrading the Boot ROM of all cards using a combined Boot ROM file. Refer to section 7.5 “Loading a Host Software Containing the Boot ROM File” on page 7-16 for details.

Assume that:

l The main boot file is SWITCH002.app.

l The active host software is SWITCH001.app.

l The Boot ROM program is SWITCHbtm.btm.

Follow these steps after logging in to the switch.

Step 1: Download the software to the switch through 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):lyt

331 Give me your password, please

Password:

230 Logged in successfully

[ftp] get Switchbtm.app Switchbtm.btm

[ftp] bye

& Note:

You can also download two copies of host software and specify one as the primary and the other as the backup.

Step 2: Load the Boot ROM.

<H3C> boot bootrom Switchbtm. btm slot 0

Board 0 upgrading BOOTROM, please wait...

Upgrade board 0 BOOTROM succeeded!

Step 3: Load the host software.

l Load the primary file.

<H3C> boot boot-loader primary SWITCH002.app

l Load the backup file.

<H3C> boot boot-loader backup SWITCH001.app

<H3C> display boot-loader

The primary app to boot of board 0 at the next time is: flash:/SWITCH002.app

The backup app to boot of board 0 is: flash:/SWITCH001.app

The app to boot of board 0 at this time is: flash:/SWITCH001.app

<H3C> reboot (Check whether other configuration is saved before restarting the system, in case the configuration is lost after the restart.)

Now you have completed the downloading of Boot ROM and host software.

Note that you must reboot the switch to validate host software downloading. If the Flash does not have enough space, you can delete some program files in the Flash after completing the Boot ROM loading. (You are recommended to delete the host program that is no longer in use.) Then you can upload the host program to the switch through FTP.

Note that the switch cannot be powered off during loading process.

7.3.2 Loading by TFTP

Remote loading by TFTP is similar to loading by FTP, except that the protocol used for downloading is TFTP. In this case, the switch can only be used as a TFTP client to download the software to its Flash from the TFTP server. After the downloading is completed, the remaining procedure is the same as that in the case of remote loading by FTP.

7.4 Booting the Switch with Dual Images

The S7502 supports dual image booting: usually the switch boots with the main image (i.e. the primary file), but uses the backup image (i.e. the backup file) instead when the main image has any error.

Refer to section 7.3 “Loading Software Remotely or Locally through Command Lines” on page 7-12 for loading dual images to the switch using commands. The following introduces the setting of dual images in Boot menu.

Step 1: Enter Boot menu.

BOOT MENU

1. Download application file to flash

2. Select application file to boot

3. Display all files in flash

4. Delete file from flash

5. Modify bootrom password

0. Reboot

Enter your choice(0-5): 2

Step 2: Type <2> to enter the menu for choosing the active booting file.

File Number File Size(bytes) File Name

========================================================

1. 4 snmpboots

2. 1972 SWITCH100.cfg

3. 1012 taskswitch.log

4. 631736 Btm530.btm

5. 199696 8241btm.app

6. 2427 cfg.txt

7. 6048565 SWITCH200.app

8(*). 5639172 SWITCH000.app

9(-). 203460 SWITCH100.app

The current application file is :SWITCH000.app

The backup application file is : SWITCH100.app

Free Space : 471040 bytes

The system shows all the files in the Flash, wherein the one with an asterisk (*) is the primary file and the one with a hyphen (-) is the backup file.

Step 3: Re-configure the primary and backup files.

l Set the primary file.

Enter the serial number of the desired primary file when the terminal shows the following information:

Please input the primary application file number to boot :9

Press <Enter>. The terminal displays the primary file name you have chosen. Type <Y> to acknowledge or <N> to reset.

The primary file you selected is SWITCH100.app, are you sure? Yes or No(Y/N):Y

If you type <Y>, the terminal displays the following information:

On reboot, SWITCH100.app will become the default primary application file to boot!

This means the primary file has been set successfully.

l Set the backup file.

You can set the backup file in a similar way you set the primary file. The terminal displays the following information:

Please input the backup application file number :7

The file you selected is SWITCH200.app, are you sure? Yes or No(Y/N)y

On reboot,SWITCH200.app will become the backup application file to boot!

Step 3: Decide whether to run the primary file immediately. If you type <Y> and press <Enter>, the system begins to reboot.

Do you want to run SWITCH100.app now?Yes or No(Y/N)?Y

press Ctrl+B to enter Boot Menu... 5

Auto-booting....................

One of the following cases may occur when the system is restarted:

l The primary file is correct and the system boots with the primary file.

l An error occurs when the system boots with the primary file, so it boots with the backup file.

l An error occurs to both the primary and backup files, so the system chooses randomly an application file for booting.

l The system stops choosing the boot file if it fails when booting with a random application file. Then it supposes that the file system is unavailable or no correct booting file is available.

& Note:

l If you specify only the primary file, and set no backup file, the system boots with the primary file. If the primary file has any error, the system randomly chooses an application file for booting.

l If you specify only the backup file, and set no primary file, the system boots with the backup file.

l If you specify neither the primary file nor the backup file, the system randomly chooses an application file for booting.

7.5 Loading a Host Software Containing the Boot ROM File

The S7502 supports multiple types of cards and these cards use different versions of Boot ROM. Thus, you are required to use the correct Boot ROM file when upgrading the Boot ROM of a card. The upgrading fails if the Boot ROM file does not match the card.

To avoid the inconvenience caused by different Boot ROM files in upgrading, Boot ROM files are combined into a host software file. That is, you can use this combined file for on-line upgrade of all cards.

A Boot ROM file is named as “*.btm”, while a host software file containing the Boot ROM file is named as “*.app”.

7.5.1 Example of Upgrading Using Combined Host Software File

I. Preset conditions

l The SRPU in slot 0 of the S7502 is LS81P12TE.

l The LPU in slot 1 is LS81FT48A.

l The host software containing the Boot ROM file is S7502.app.

l Both online upgrading through command line and upgrading through Boot Menu use FTP mode.

Step 1: Download the host software that supports the combined Boot ROM file to the switch through FTP.

<H3C> ftp 10.10.110.1

[ftp] get S7502.app

[ftp] bye

Step 2: Specify S7502.app as the application software used by the switch for the next boot.

<H3C> boot boot-loader primary S7502.app

Step 3: Reboot the switch to make the S7502.app effective.

<H3C> reboot

Step 4: Upgrade the Boot ROM of the SRPU and LPU using the combined host software file.

<H3C> boot bootrom S7502btm.btm slot 0 1

Upgrade board 0 BOOTROM succeeded!

Board 1 upgrading BOOTROM, please wait...

Load finished!

Start Upgrading...

Frame 0 IO Board 1 upgrade BOOTROM succeeded!

By now, you have completed the Boot ROM upgrade.

7.6 Handling Loading Failure

If loading fails, the system runs the original version.

To handle a loading failure, proceed as follows:

1) Check whether the physical ports are correctly and well connected.

l If no, reconnect them correctly and restart the loading process.

l If yes, go to step 2.

2) Check the loading information for the following input errors on the HyperTerminal:

l If the XModem is used for loading, the baud rate of the HyperTerminal is not changed back to 9600bps after you load the software by using a baud rate other than 9600 bps.

l If the TFTP or FTP is used for loading, the IP address of server or switch, the name of the file to be downloaded, or the working path of TFTP server is wrong.

3) If loading fails when the physical connection is normal and no input errors are found, contact the local agents of Hangzhou H3C Technologies Co., Ltd. for help.

7.7 Handling Password Loss

If you lose the Boot ROM password of the switch, contact the local agents of Hangzhou H3C Technologies Co., Ltd.
