1.1 Configuring Boot ROM Upgrade with App File

By enabling Boot ROM to upgrade together with the app file, you can ensure that the

Boot ROM versions of the current SRPU and service cards match the version of the

current app file, thus avoiding invalid feature implementation caused by mismatching.

Two upgrade types are available:

z The current startup file as the upgrade file for Boot ROM

z The specified App file as the upgrade file for Boot ROM

1.1.1 Boot ROM Upgrade Configuration

Follow these steps to configure Boot ROM upgrade

To do... Use the command... Remarks

Set the current startup file as the

upgrade file for Boot ROM

boot bootrom default [ slot

slot-number-list ]

Optional

Set the specified App file as the

upgrade file for Boot ROM

boot bootrom file-url [ slot

slot-number-list ]

Optional

Set the primary startup file at next

booting and use it to upgrade Boot

Caution:

z If you do not specify a slot number in the boot bootrom command, the system

upgrades all normal boards in position by default.

z After you specify the primary startup file for the next booting, the system upgrades

all normal boards in the process of upgrading Boot ROM. You need also to confirm

the upgrade operation in the upgrade process.

1.1.2 Boot ROM Upgrade Configuration Example

I. Network requirements

z Use the current startup file to upgrade the Boot ROMs of all normal LPU boards in

position.

z Use the specified App file (abcd.app) to upgrade the Boot ROMs of all normal

LPU boards in position.

z Specify the App file abcd.app as the primary startup file for next booting and use it

to upgrade the Boot ROMs.

II. Configuration example

# Use the current startup file to upgrade the Boot ROMs of all normal LPU boards in

position.

<H3C> boot bootrom default

# Use the specified App file (abcd.app) to upgrade the Boot ROMs of all normal LPU

boards in position.

<H3C> boot bootrom abcd.app

# Specify the App file abcd.app as the primary startup file for next booting and use it to

upgrade the Boot ROMs.

<H3C> boot boot-loader primary abcd.app

1.2 Configuring Inter-Card Link State Adjustment

1.2.1 Introduction

The inter-card link state adjustment function is designed to improve the adaptability of

the inter-card links in an S7500 series switch. It enables you to set the mode in which

inter-card links are established as needed.

 Note:

An inter-card link refers to the internal links between the SRPU and all the service cards

of an Ethernet switch.

Inter-card links can be established in one of the following two modes:

z Auto-negotiation mode, where inter-card links are established through negotiation

to improve the adaptability and stability. This mode is based on the corresponding

Ethernet standards. By default, the SRPU and the service cards in an S7500

series Ethernet switch negotiate to establish 1000 Mbps links in between.

z Fix mode, where 1000 Mbps links are established between the SRPU and the

service cards without negotiation. Therefore, the time for negotiation is saved. For

the switches operating as network nodes, establishing inter-card links in this mode

improves the response speed and reduces the influence on access devices when

board switchovers occur.

 Note:

Since the two modes have no affect on the performance, it is unnecessary to modify the

existing configuration when you employ this function.

1.3 Configuring Internal Channel Monitoring

1.3.1 Introduction

An internal channel refers to the interface channel between the SRPU and the service

cards. The SRPU sends handshake packets to each service card every second. After

receiving the handshake packets, the service cards report the result to the SRPU. In

Chapter 1 Hardware-Dependent

this case, the SRPU knows that the service cards are operating normally. Through this

process, the SRPU can judge whether each service card in the device operates

normally.

S7500 Ethernet switches support this feature. Through this feature, you can monitor

internal channels.

You can also set the maximum number of times the SRPU fails to receive handshake

packets. If the number of times the SRPU fails to receive handshake packets exceeds

the upper limit, the switch resets the processing chip automatically. When the SRPU

receives handshake packets, it resets the counter automatically.

You can also set whether to restart the service card or the switch when the number of

times the SRPU fails to receive handshake packets exceeds the upper limit.

1.4 Configuring Switch Chip Auto-Reset

1.4.1 Introduction

In actual application, a switch may fail to process services normally due to internal

channel block or because the switch chip is busy.

The S7500 series switches support the function of resetting switch chips automatically.

In case that the function of monitoring internal channels is enabled, when the internal

channel handshake between a card and the backplane fails, the switch resets the

switch chip automatically to resume the corresponding card.

When the function of resetting switch chips is disabled, even if the switch finds that the

internal channel handshake fails, it cannot reset the switch chip automatically.
