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:
zThe current startup file as the upgrade file for Boot ROM
zThe 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
ROM
boot boot-loader primary
file-url Optional

Caution:
zIf you do not specify a slot number in the boot bootrom command, the system
upgrades all normal boards in position by default.
zAfter 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
zUse the current startup file to upgrade the Boot ROMs of all normal LPU boards in
position.
zUse the specified App file (abcd.app) to upgrade the Boot ROMs of all normal
LPU boards in position.
zSpecify 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.

Operation Manual – Hardware-Dependent Software Configuration
H3C S7500 Series Ethernet Switches Chapter 1 Hardware-Dependent Software Configuration
1-3
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:
zAuto-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.
zFix 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

Operation Manual – Hardware-Dependent Software Configuration

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.
