l The Boot ROM version must match the host software version when you load a Boot ROM and host software. You are recommended to upgrade the Boot ROM only when the host software to be loaded does not match the existing Boot ROM version. Frequent Boot ROM loading is discouraged.

l You can use the Boot Menu to load a Boot ROM and host software of only SRPUs. To load a Boot ROM of LPUs, you must use command lines.

7.1.2 Loading Software through Command Lines

You can load software through command lines using:

l FTP

l TFTP

7.2 Loading Software Through the Boot Menu

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

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

& Note:

You can follow the same procedure to load a Boot ROM and host software, except that in a Boot ROM loading process you need to press Ctrl + U and Enter and will view different prompt information after entering the Boot menu. All loading procedures described in this chapter focus on how to load a Boot ROM.

7.2.1 BOOT Menu

7.2.2 Loading Software from the Console Port Using Xmodem

I. Introduction to Xmodem

The Xmodem protocol is a file transfer protocol widely applied due to its simplicity and performances. Xmodem transfers files through the console port. It supports 128-byte or 1-kilobyte packets, checksum, CRC, and retransmissions (generally 10 times) in case of packet errors.

XModem transmission works through a receiving program and sending program. The receiving program first sends a negotiation character requesting for a check method. The sending program starts data packet transmission if the negotiation succeeds. After receiving a complete packet, the receiving program checks the packet using the negotiated check method. If the check succeeds, the receiving program sends a positive acknowledgement character and the sending program continues to send the next packet. If the check fails, the receiving program sends a negative acknowledgement character and the sending program retransmits the packet.

7.3 Loading Software Through Command Lines

7.3.1 Loading Using FTP

Run the FTP Server on a 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 S7500 series support dual image booting. That is, the S7500 series normally boot with the main image (i.e. the primary file), but with the backup image (i.e. the backup file) when errors occur to the primary one. Refer to section 7.5 “Booting the Switch with Dual Images” on page 7-17 for details.

l The S7500 series also support the upgrade by using host software containing the Boot ROM file. That is, you can upgrade the Boot ROM of all boards using such host softwware. Refer to section 7.6 “Loading Host Software Containing the Boot ROM File” on page 7-19 for details.

Assume that:

l The main boot file is SWITCH002.app.

l The host software running on the switch is SWITCH001.app.

l The Boot ROM program is SWITCHbtm.btm.

Follow these steps after logging in to the switch.

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

Password:

230 Logged in successfully

[ftp] get SWITCH002.app SWITCH002.app

[ftp] get Switchbtm.app Switchbtm.btm

[ftp] bye

& Note:

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

2) Load the Boot ROM.

<H3C> boot bootrom Switchbtm.btm slot 0

Board 0 upgrading BOOTROM, please wait...

Upgrade board 0 BOOTROM succeeded!

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 rebooting the system, in case the configuration is lost after the reboot.

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 memory is not large enough, you can delete some program files (for example, the host program that is no longer in use) from the Flash memory after loading the Boot ROM. Then you can upload the host program to the switch through FTP. Do not power off the switch during the loading process.

7.3.2 Loading using TFTP

Loading using TFTP is similar with loading using 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 memory from the TFTP server. After the downloading is completed, the remaining procedure is the same as that in the case of loading using FTP.

7.4 Loading Boot ROM and Host Software to the S7506R

The H3C S7506R is equipped with two SRPUs. Slots 0 and 1 are for SRPUs and the rest slots are for LPUs. Thus, loading Boot ROM and host software to the S7506R involves loading Boot ROM and host software to the active and standby SRPUs, and loading Boot ROM to LPUs.

The following two loading approaches are available on the S7506R:

l Loading through command lines

l Loading through the BOOT menu

However, you can load a Boot ROM to LPUs only through command lines.

When loading a Boot ROM or host software, note that:

l To keep consistent the software versions of the active SRPU, standby SRPU, and LPUs, use the same approach (either command lines or BOOT menu) to load the Boot ROM or host software to the active and standby SRPUs.

l If the current Boot ROM matches the host software to be loaded, you do not need to load the Boot ROM to the active SRPU, standby SRPU, and LPUs.

& Note:

Loading through command lines affects switch services less significantly than loading through the BOOT menu. You are recommended to load a Boot ROM or host software through command lines.

7.4.1 Loading Through Command Lines

Assume that:

l The target Boot ROM is BTM530.btm.

l The primary boot file is S7506R002.app and the host software running on the switch is S7506R001.app.

l The active SRPU is inserted in slot 0, the standby SRPU in slot 1, and an LPU in slot 3.

I. Loading using FTP

Run the FTP Server on the local computer. Check whether a username, a password, and the correct file directory have been configured. Log in to the switch through Telnet or through the console port and transfer host software to the switch using FTP.

1) Download program files to the switch using FTP

<H3C> ftp 10.10.110.1

Trying ...

Press CTRL+K to abort

Connected.

[ftp] bye

2) Load the Boot ROM (Skip this step if Boot ROM loading is not required).

& Note:

If you need to load a Boot ROM to the LPU as well as SRPUs, load the Boot ROM to the LPU first and then to the active and standby SRPUs.

l Load the Boot ROM to the LPU.

<H3C> boot bootrom BTM530.btm slot 3

This will update BootRom file on board 3 . Continue? [Y/N] y

Type Y and press Enter. The terminal displays the following information:

Board 3 upgrading BOOTROM, please wait...

Load finished!

Start Upgrading...

Frame 0 IO Board 3 upgrade BOOTROM succeeded!

<H3C>

l Load the Boot ROM to the active SRPU.

<H3C> boot bootrom SRPUbtm.app slot 0

Board 0 upgrading BOOTROM, please wait...

Upgrade board 0 BOOTROM succeeded!

3) Load host software to the active SRPU.

l Load the primary file.

<H3C> boot boot-loader primary S7506R002.app slot 0

l Load the backup file.

<H3C> boot boot-loader backup S7506R001.app slot 0

<H3C> display boot-loader

The primary app to boot of board 0 at the next time is: flash:/S7506R002.app

The backup app to boot of board 0 is: flash:/S7506R001.app

The app to boot of board 0 at this time is: flash:/S7506R001.app

4) Load the Boot ROM and host software to the standby SRPU.

l Copy the Boot ROM and host software from active SRPU to the standby one.

<H3C> copy S7506R002.app slot1#flash:/S7506R002.app

l Specify the newly loaded Boot ROM and host software as the Boot ROM and host software of the standby SRPU.

<H3C> boot bootrom SRPUbtm.app slot 1 (Skip this if Boot ROM loading is not required.)

<H3C> boot boot-loader primary S7506R002.app slot 1

<H3C> boot boot-loader backup S7506R001.app slot 1

<H3C> display boot-loader

The primary app to boot of board 0 at the next time is: flash:/S7506R002.app

The backup app to boot of board 0 is: flash:/S7506R001.app

The app to boot of board 0 at this time is: flash:/S7506R001.app

The primary app to boot of board 1 at the next time is: flash:/S7506R002.app

The backup app to boot of board 1 is: flash:/S7506R001.app

The app to boot of board 1 at this time is: flash:/S7506R001.app

5) Restart the system.

<H3C> reboot

II. Loading using TFTP

Loading using TFTP is similar to loading using 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 loading using FTP.

7.4.2 Loading through the BOOT Menu

To load a Boot ROM and host software to the active and standby SRPUs of the S7506R through the BOOT menu, you can use the same loading method for the switches that only support a single SRPU, as described in section 7.2 “Loading Software Through the Boot Menu” on page 7-1.

Note that:

l You are recommended to use two HyperTerminals to connect the console ports of active and standby SRPUs. In this way, you can load Boot ROM and host software to active and standby SRPUs simultaneously. After loading, reboot the system, or reboot the active and standby SRPUs separately.

l If only one HyperTerminal is available, you can load the Boot ROM and host software to the active SRPU and reboot it. Then connect the HyperTerminal to the console port of the standby SRPU, load the Boot ROM and host software to the standby SRPU, and then reboot it.

l After the system reboots, load the Boot ROM to the LPUs through command lines. For more information, refer to section 7.4.1 “Loading Through Command Lines” on page 7-14.

Caution:

l The software of the SRPUs and LPUs must be consistent so that the S7500 series can work normally.

l After loading the host software of the SRPUs of the S7500 series, you must reboot the LPUs to synchronize the software of the LPUs with that of the SRPUs.

l The S7506R supports dual SRPU design and active-standby switchover. If two SRPUs are equipped, you can use the active-standby switchover function to update and reboot the two SRPUs in turn on condition that one SRPU works normally. Although the SRPUs support hot backup, you are recommended to reboot the whole system after loading the software of the SRPUs because LPUs must be rebooted to keep their software version consistent with that of the SRPUs and the services will be interrupted during LPU reboot.

7.5 Booting the Switch with Dual Images

The S7500 series support dual image booting. That is, the switch normally boots with the main image (i.e. the primary file), and with the backup image (i.e. the backup file) when errors occur to the main image.

Refer to section 7.3 “Loading Software 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 the Boot menu.

1) Enter the 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

2) Select 2 and press Enter.

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

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 displays the following information:

Please input the primary application file number to boot :9

Press Enter and the terminal displays the primary file name you have chosen. Type Y to confirm the choice or N to reset.

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

If you enter 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 almost in the 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!

4) 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 rebooted:

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 any application file if it fails to boot with a random application file. Then it supposes that the file system is unavailable or no correct boot file is available.

& Note:

l If you specify only the primary file, but no backup file, the system boots with the primary file. If the primary file is corrupted, the system randomly chooses an application file for booting.

l If you specify only the backup file, but 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.

7.6 Loading Host Software Containing the Boot ROM File

The S7500 series support multiple types of boards and these boards use different versions of Boot ROM. Thus, you are required to use the correct Boot ROM file when upgrading the Boot ROM of a board. The upgrading will fail if the Boot ROM file does not match the board.

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 boards.

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

7.6.1 Example of Upgrade Using Host Software Containing Boot ROM Files

I. Preset conditions

l The SRPU in slot 0 of the S7506 is LS81SPRG.

l The LPU in slot 3 is LS81FT48A and the LPU in slot 4 is LS82GT20. There are no LPUs in the other slots.

l The host software containing Boot ROM files is S7506.app.

l Both online upgrading through command lines and upgrading through the Boot menu use FTP.

1) Download the host software containing Boot ROM files to the switch using FTP.

<H3C> ftp 10.10.110.1

[ftp] get S7506.app

[ftp] bye

2) Specify S7506.app as the application file used by the switch for the next boot.

<H3C> boot boot-loader primary S7506.app

3) Reboot the switch to validate the S7506.app file.

<H3C> reboot

4) Upgrade the Boot ROM of each LPU and the SRPU using the host software.

<H3C> boot bootrom S7506btm.btm slot 0 3 4

Upgrade board 0 BOOTROM succeeded!

Board 2 upgrading BOOTROM, please wait...

Load finished!

Start Upgrading...

Frame 0 IO Board 2 upgrade BOOTROM succeeded!

Board 3 upgrading BOOTROM, please wait...

Load finished!

Start Upgrading...

Frame 0 IO Board 3 upgrade BOOTROM succeeded!

Board 4 upgrading BOOTROM, please wait...

Load finished!

Start Upgrading...

Frame 0 IO Board 4 upgrade BOOTROM succeeded!

By now, you have completed the Boot ROM upgrade.

7.7 Handling Loading Failure

If loading fails, the original version will still run on the system.

To handle a loading failure, proceed as follows:

1) Check whether the physical ports are correctly connected.

l If no, reconnect them and restart loading.

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.
