Chapter 1 DIMM Module Installation of H3C S7500 Salience III Series
1.1 S7502 Series Ethernet Switches
Caution:
As the SRPU of an S7502 series Ethernet switch is not needed to be upgraded using the DIMM modules of Salience III series SRPUs, DIMM modules are not included in the software upgrade package shipped with S7502 series switches.
1.2 S7503/S7506/S7506R Series Ethernet Switch
Caution:
l The LS81PT8GA board can only cooperate with Salience III or Salience III Edge engine.
l If you do not expand the memory of a Salience III series SRPU by installing new DIMM modules, EPON services may not operate with other services simultaneously due to lack of memory space.
l As an S7506R switch contains two SRPUs, be sure to upgrade the two SRPUs at same time.
l To upgrade a Salience III series SRPU, use the DIMM modules provided by Huawei-3Com Technology Co., Ltd. and intended for Salience III series SRPUs only.

1.2.2 Installing a DIMM Module
Follow the instructions described in the following sections to install DIMM modules for Salience III series SRPUs.
I. Determining the socket for the DIMM module
For a Salience III series SRPU, DIMM modules are installed in the U36 sockets (the following operation assumes that the SRPU has a 256 M DIMM module installed.)
Figure 1-2 Position of the DIMM module
II. Installation steps
1) Loosen the locking spring clips of the U36 socket to turn out the 256 M DIMM module.
2) Remove the 256 M DIMM module.
3) Take the Salience III series SRPU 512 M DIMM module out of the software upgrade package.
4) Insert the DIMM module into the corresponding DIMM socket and close the locking spring clips.
& Note:
l With the reverse insertion prevention design, you surely can insert the DIMM module in right direction.
l If the DIMM module of Salience III series is not fully seated, the SRPU cannot function well.
1.2.3 Precautions
To prevent components of SPRU from being damaged, be sure to wear an ESD-protective wrist strap when installing DIMM modules for Salience III series SRPUs.
Chapter 2 Upgrading EPON Software
& Note:
l H3C S7500 Series Ethernet Switches serves as the OLT in EPON systems.
l You can load host software to the H3C S7500 Series Ethernet Switches through CLI (command line interface) or the BOOT menu.
l Before upgrade EPON software, you need to copy EPON software upgrading program (contained in the accompanied CD) to the user terminal.
2.1 Ways to Load Host Software
The following are available to load host software through CLI:
l FTP
l TFTP
The following are available to load host software locally through BOOT menu:
l XModem (through Console port)
l TFTP (through Ethernet port)
l FTP (through Ethernet port)
& Note:
l Loading host software using XModem through Console port is time-consuming and is thus not recommended.
l The commands, interfaces and temrinal information here ivolved in the downloading process are only for reference, and the actual ones may differ.
2.2 Loading Host Software Locally/Remotely through CLI
If your terminal is connected to the switch through a network, you can load the host software remotely.
Caution:
When loading host software in this way, make sure the IP addresses of both the switch and you PC are in the same network segment.
I. Remote and local loading using FTP
Configure the local PC as an FTP server (with user name, password, and the path of the host software configured), telnet to the the switch or connect the PC to the Console port, and then transmit the host software to the switch using FTP.
& Note:
An S7500 series Ethernet switch support dual image booting. When a switch fails to start using the the main image (that is, the primary file), the backup image (that is, the secondary file) is used. See 2.5 Booting the Switch with Dual Images for details.
The following operation transmits the host software to a switch and starts the switch, with the assumption that the main boot file is SWITCH002.app; the currently active host software is SWITCH001.app, and the IP address of the FTP server is 10.10.110.1.
Step 1: Download the host software to the switch using FTP.
<H3C> ftp 10.10.110.1
Trying ...
Press CTRL+K to abort
Connected.

[ftp] bye
& Note:
You can also download two host software images: one as the primary and the other as the secondary.
Step 2: Load the host software.
l Load the primary file
<H3C> boot boot-loader primary SWITCH002.app
l Load the secondary 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 (Make sure that you have saved other configurations before rebooting, otherwise, they might not survive a reboot.)
Host software loading is completed now. Note that you must reboot the switch to validate host software downloaded. If Flash memory space is not enough, you can delete some of the program files in Flash (such as those that are no longer in use) before uploading the host software to the switch using FTP. Also note that power-off ruins the entire loading process.
II. Remote and local loading using TFTP
Using TFTP to load host software is the same to that of FTP except that TFTP rather than FTP is used to transmit host software to the switch. In this case, the switch can only operate as a TFTP client to download the host software to its Flash memory from the TFTP server.
2.3 Local Software Loading through BOOT Menu
If the user terminal is directly connected to the switch, you can load the host software locally.
Before proceeding to load the software, make sure that the user terminal is correctly connected to the switch.
I. BOOT menu
After powering on the switch, the BOOTROM program is launched and the terminal will display the following information:

II. Loading software through Console port using XModem
1) Introduction to XModem
XModem is a file transfer protocol widely used due to its simplicity and satisfactory performance. XModem transfers files through 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 ten.
XModem transmission is completed by receiving program and sending program. Receiving program initiates packet checking method negotiation by sending the negotiation character. If the negotiation passes, sending program starts packet transmission. Upon the receipt of a complete packet, the receiving program checks it using the agreed-upon check 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.

2.4 Loading Host Software to S7506R
H3C S7506R uses dual SPRUs, one of which is active (hereinafter referred to as master card) and the other one is standby (hereinafter referred to as slave card). The slots 0 and 1 are fixedly for SRPUs, while other slots are for LPUs. The loading to S7506R includes host software loading to master card and slave card.
The following two loading approaches are available on S7506R:
l Remote or local loading through CLI
l Local loading through BOOT menu
Note that to keep consistent software version of master card, slave card and LPUs, use the same approach to load corresponding contents to the master and slave cards. That is, both through CLI or both through BOOT menu.
& Note:
Since loading through CLI has less affect on the switch services than loading through BOOT menu, CLI is preferred.
Caution:
The IP addresses of the switch and the PC on which the software file is loaded must be of the same network segment.
I. Loading through CLI
Suppose that the host software is S7506R002.app and the currently active host software is S7506R001.app. The master card is inserted in slot 0, the slave card in slot 1, and a LPU in slot 3.
1) Loading through FTP
Configure the local PC as an FTP server (with username, password and the path of the host software configured), telnet to the switch or connect the PC to the Console port, and then transfer host software to the switch through FTP. (Suppose the IP address is 10.10.110.1).
Step 1: Download program files to the switch using FTP
<H3C> ftp 10.10.110.1
Trying ...
Press CTRL+K to abort
Connected.

Step 2: Load host software to master card.
l Load the primary file
<H3C> boot boot-loader primary S7506R002.app slot 0
l Load the secondary 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
Step 4: Load host software to slave card.
l Copy host software from master card to slave card.
<H3C> copy S7506R002.app slot1#flash:/S7506R002.app
l Specify the newly loaded host software as the host software of slave card.
<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
Step 5: Reboot the system.
<H3C> reboot
2) Loading through TFTP
Using TFTP to load host software is the same to that of FTP except that TFTP rather than FTP is used to transmit host software to the switch. In this case, the switch can only operate as a TFTP client to download the host software to its Flash memory from the TFTP server.
II. Loading through BOOT menu
Loading corresponding contents to master and slave cards for S7506R through BOOT menu is the same as that for S7506 and S6503. Refer to 2.2 Loading Host Software Locally/Remotely and 2.3 Local Software Loading through BOOT Menu for details. Note that:
l It is recommended that you use two HyperTerminals which are connected respectively to the Console ports of master and slave cards to simultaneously load host program to master and slave cards. After loading, reboot the system or reboot master and slave cards separately.
l If only one HyperTerminal is available, you can first load the contents to master card and reboot it. Then connect the HyperTerminal to the Console port of slave board and load host software to slave card and reboot it.
2.5 Booting the Switch with Dual Images
The S7500 series support dual image booting: Usually the switch boots with the main image (i.e. the primary file), but it uses the secondary image (i.e. the backup file) when the main image is in error. BOOTROM 400 or above version is required to support dual image booting.
Refer to section 2.3 Local Software Loading through BOOT Menu 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: Enter <2> to turn to the menu for choosing the active booting file.
File Number File Size(bytes) File Name
=======================================================1. 4 snmpboots

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 memory, where the one with the asterisk (*) is the primary file and the one with the hyphen (-) is the secondary file.
Step 3: Reset the primary and secondary 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> and the system displays the primary file name you have chosen. Type <Y> to acknowledge and <N> to reset.
The primary file you selected is SWITCH100.app, are you sure? Yes or No(Y/N):Y
Type <Y> (as an example) and the terminal show this 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 secondary file
You can set the secondary file in almost the same way as setting the primary file. The terminal shows the following information in this case:
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 if to run the primary file immediately. Ether <Y> and 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....................
These may occur in your system booting:
l The primary file is correct and the system boots with the primary file.
l A fault occurs when the system boots with the primary file, so it boot with the secondary file.
l Both the primary and backup files are in error, so the system chooses randomly an application file for booting.
l The system stops choosing boot file if it fails when booting with a random application file. Then it just reckons this as that the file system is unavailable or no correct booting file is available.
& Note:
l If you specify only the primary file, but not the secondary file, the system boots with the primary file. If the primary file is in error, the system randomly chooses an application file for booting.
l If you specify only the secondary file, but not the primary file, the system boots with the secondary file.
l If you specify neither the primary file nor the backup file, the system randomly chooses an application file for booting.
2.6 Dealing with Load Failures
If loading fails, the original version will remain in the system.
In this case, check that the physical ports are correctly and well connected. If they are not, reconnect them correctly and restart loading procedures.
If there are no problems with the physical connections, please carefully check information about the loading procedures for input errors on the HyperTerminal.
When using XModem, check that you have reset the baud rate of the HyperTerminal to 9600 bps after loading the software with a baud rate other than 9600 bps;
1) When using TFTP, check that you have provided:
l Correct server and switch IP addresses;
l Correct name of the software to be loaded;
l Correct path for TFTP Server to operate on program files.
2) When using FTP, check that you have provided:
l Correct server and switch IP addresses;
l Correct name of the software to be loaded;
l Correct username and password.
If loading fails when there are neither physical connection problems nor input errors, please contact the local agents of Huawei-3Com Technology Co., Ltd. for help.
2.7 Dealing with Missing of Password
Please contact the local agent if the BOOTROM password or user password of the switch is lost.
