Combo interfaces

1) Introduction
The A6602 provides four Combo interfaces. Each Combo interface consists of an electrical

Ethernet interface and an optical Ethernet interface, but either the electrical Ethernet interface
or the optical Ethernet interface can operate at one time.

Each fixed electrical Ethernet interface supports 10/100/1000 Mbps auto-sensing. For the rate
and duplex for the electrical Ethernet interfaces, see Table 1-14.

Table 1-14 Rate and duplex for the electrical Ethernet interfaces

Rate Duplex

10 Mbps (auto-sensing) Half/full-duplex auto-negotiation
100 Mbps (auto-sensing) Half/full-duplex auto-negotiation
1000 Mbps (auto-sensing) Full-duplex

The electrical Ethernet interface LEDs are above the RJ-45 ports. The LEDs in triangle and
inverted triangle indicate the status of the lower and upper electrical Ethernet interfaces,
respectively.

Each optical Ethernet interface supports a rate of 1000 Mbps in full-duplex mode. The optical
Ethernet interface LEDs are in the middle of the four Combo interfaces and use separate LEDs
to indicate the status of the corresponding SFP interfaces.

 For a Combo interface, the default operating interface is the Ethernet electrical interface.
 For a Combo interface, you can use either the electrical Ethernet interface or the optical

Ethernet interface. You can use the combo enable { copper | fiber } command in interface
view to switch between the optical and electrical Ethernet interfaces.

 For details about the combo enable { copper | fiber } command, refer to HP SR6600 Routers

User Manual.

 The media dependent interface (MDI) standard is typically used on the Ethernet interface of

network adapters. The media dependent interface crossover (MDI-X) standard is typically used
on hubs or LAN switches.

 When 10/100 Mbps and half duplex/full duplex are specified for an electrical Ethernet interface,

the electrical Ethernet interface operates in the forced mode. When 1000Mbps is specified or
the rate and the duplex mode are not simultaneously specified for an electrical Ethernet
interface, the electrical Ethernet interface operates in the auto-negotiation mode.

 An electrical Ethernet interface supports automatic MDI/MDI-X in both the forced mode and the

auto-negotiation mode; namely, it supports both straight-through and crossover cables.

 Standard cable: Also called straight-through cable. At both ends of a standard cable, wires are

crimped in the RJ-45 connectors in the same sequence. A straight-through cable is used to
connect a terminal (for example, PC or router) to a hub or LAN Switch. The cables delivered
with the A6602 are straight-through cables.

 Crossover cable: At both ends of a crossover cable, wires are crimped in the RJ-45 connectors

in different sequences. A crossover cable is used to connect a terminal (for example, a PC or
router) to another terminal. You can make crossover cables by yourself as needed.

You can use a single-mode or multi-mode optical fiber to connect a 1000 Mbps optical Ethernet

interface to an Ethernet. You can select proper fibers for the installed 1000Base-FX SFP
transceiver (GE SFP for short). Since the optical interfaces on these SFP transceivers use LC

optical connectors, you must use fibers with LC connectors. All SFP transceiver are hot­swappable.

 No SFP module is shipped with the A6602 unless ordered.
 Use only the SFP modules provided by HP. The A6602 cannot identify SFP modules from other

manufacturers.

 For the connection of electrical Ethernet interface or optical Ethernet interface cables, refer to

“Connecting Ethernet Cables” in Chapter 3 “Installing the Router”.

USB Interfaces

The universal serial bus (USB) interfaces can connect multiple types of devices and provide a
higher data transfer rate than common parallel interfaces and serial interfaces.

The A6602 fully supports USB 1.1. The USB interfaces on the router provide important storage
and security functions. For example, they provide large Flash memory space for application
programs, configuration files, and security VPN certificates to establish secure VPN connections
and secure the delivery of router configuration files.

In addition, USB interfaces provide a backup CF card mechanism to make file backup and
restoration very convenient and reliable.

Figure 1-12 USB Interfaces

USB0

USB interface 0 on the A6602 is a USB 1.1-compliant type-A interface. USB interface 0 can be
connected to an external USB storage device to expand the router’s space for storing files and
logs and facilitate file transfer.

Insert and remove a USB storage device correctly. Otherwise, the software, hardware and file
system of the USB storage device may get damaged.

 After you insert a USB storage device and information is displayed on the terminal, prompting

the USB storage device is inserted into the A6602, the LED on the USB storage device will be
on.

 When the LED on the USB storage device is blinking, do not remove the USB storage device.

Before removing the USB storage device, execute the umount usba0: command in user view
to unmount the USB storage device. If information is displayed on the terminal, prompting the
USB storage device is successfully unmounted, you can remove the USB storage device. After
the USB storage device is removed, information will also be displayed on the terminal, showing
the USB storage device has been removed.

 The A6602 only supports the USB storage devices provided by HP and may be incompatible

with those from other manufacturers.

 For details about the umount command, refer to HP SR6600 Routers User Manual.

USB1

USB interface 1 on the A6602 is a USB 1.1-compliant type-B interface. USB interface 1 can be
connected to a terminal or computer through a standard cable. After the interface is enabled,
the built-in CF card of the A6602 is recognized as an external storage device by the computer
and you can access the internal CF card quickly and perform file operations on it.

Table 1-19 describes the USB interface 1 LED.

Table 1-19 Description of USB interface 1 LED

Status Meaning

Solid green A link is present.
Blinking green Data is being received or transmitted. In this state, do not unplug the USB cable.

Interface Modules

The A6602 provides two HIM/MIM slots, in which you can insert a HIM and a MIM, or two HIMs,
or two MIMs. HIMs and MIMs are hot-swappable.

 For the installation and removal of HIMs and MIMs, refer to Chapter 6 “Maintaining Hardware”.
 “Hot-swapping” a module refers to first using the remove slot number command to stop the

module and then pulling it out manually, or inserting the module into its slot without powering off
the device.

AC Power Input

Table 1-20 lists the AC input power specifications for the A6602.

Table 1-20 AC input power specifications for the A6602

Item Specification

Rated voltage range 100 VAC to 240 VAC; 50 Hz or 60 Hz
Maximum input current 2.5 A
Maximum power 150 W

Clock

The A6602 router is designed with a clock module that provides the system time. You can set
the system time on the command line interface.

Use the clock datetime time date command in user view to set the system date and time. For
the description of the clock datetime command, refer to HP SR6600 Routers User Manual.

When a power failure occurs to the router, the clock module can continue working to ensure the
system time is correct next time the router boots. With the router powered off, the clock module
can work for at least 10 years.

When the router is powered on, pay attention to the following points:

 Never replace the clock module battery.

The system time gets lost once the battery of the clock module is removed, and you need to set
the system time again on the command line interface. However, the system time will still get lost
after the router is powered off.

You can use the clock datetime, clock summer-time one-off (or clock summer-time
repeating), and clock time zone commands to set the system date and time. For details about
these commands, refer to HP SR6600 Routers User Manual.

RPS (Optional)

The redundancy power supply (RPS) can provide power supply to maintain the normal system
operation for a short period when the system power supply fails.

The RPS uses a control pin to control its output status. When the system power supply fails, it
sends a LOW signal to the control pin of the RPS. Upon receiving the LOW signal, the RPS
switches to the output status within 10 ms and starts to supply power to the router.

The A6602 supports AC power input and RPS input. They can guarantee the router to continue
working when one power supply fails, thus providing high reliability.

Table 1-21 Specifications for the RPS of the A6602

Specification Value

Rated output voltage 12 V
Maximum output current 14 A
Maximum output power 168 W

 The RPS is an optional component not shipped with the router.
 For the RPS installation, refer to “Connecting the RPS DC Power Cable” in Chapter 3 “Installing

the Router”.

Port Lightning Arrester (Optional)

Before connecting an outdoor Ethernet cable to an Ethernet port, you can install a port lightning
arrester to protect the router against lightning strokes.

The following port lightning arrester can be installed on the A6602. The specifications for the
port lightning arrester are as follows:

Port protective unit–single port, maximum discharge current (8/20μs waveform): 5 kA, output
voltage (10/700μs waveform): core-core < 40 V, core-ground < 600 V.

For the installation of the port lightning arrester, refer to “Installing a Port Lightning Arrester
(Optional)” in Chapter 3 “Installing the Router”.

Power Lightning Arrester (Optional)

Before connecting an outdoor AC power supply to the router, you need to install a lightning
protection busbar at the AC power input end and then connect the AC power cord to the
lightning protection busbar to protect the router against lightning strokes. In a heavy lightning
area, you are recommended to install a power lightning arrester.

The following power lightning arrester can be installed on the A6602. The specifications for the
power lightning arrester are as follows:

Maximum discharge current: 6500 A, protection voltage: 220 VAC to 500 VAC.

For the installation of the power lightning arrester, refer to “Installing a Power Lightning Arrester
(Optional)” in Chapter 3 “Installing the Router”.

Signal Lightning Arrester (Optional)

Generally, you need to connect a signal lightning arrester (namely, a transient over-voltage
protection) before connecting a signal cable to the router. This can protect electronic devices
against surge over-voltage resulting from lightning strokes and other interferences, and
minimize impact on the router.

The A6602 supports three types of signal lightning arresters:

 Voltage-limiting protection-signal lightning arrester-maximum discharge current

2.5KA/protection voltage 25V--SMB-75J/SMB-75J-1W-10Mbps.

 Voltage-limiting protection-signal lightning arrester-maximum discharge current

2.5KA/protection voltage 25V-BNC-75K/BNC-75K-10Mbps.

 Voltage-limiting protection-signal lightning arrester (U port)-maximum discharge current

3KA/common mode 400 V/differential mode 170V-RJ11.

For the installation of the signal lightning arrester, refer to “Installing a Signal Lightning Arrester
(Lightning Protection Busbar) (Optional)” in Chapter 3 “Installing the Router“.

System Software

The A6602 uses the Comware V5 software platform, HP's core software platform.
Based on the IPv4/IPv6 dual stack, the Comware V5 software platform integrates data

communications features such as link-layer protocols, Ethernet switching, intelligent resilient
framework (IRF), routing, Multi-Protocol Label Switching (MPLS), Virtual Private Network (VPN),
Quality of Service (QoS), security and multicast. It is one of the most mature network operating
systems. The Comware V5 software platform is scalable and portable because it adopts a
componentized architecture and effectively encapsulates and masks different operating
systems and hardware.

2 Preparing for Installation

Environment Requirements

The A6602 is designed for indoor application. To ensure the normal operation and prolong the
service life, the installation site must meet the requirements mentioned hereunder.

Temperature and Humidity Requirements

The temperature and humidity in the equipment room shall be maintained at an appropriate
level.

 A long-term high relative humidity will quite likely result in poor insulation

performance, electric leakage, mechanical property change, and corrosion.

 A long-term low relative humidity will result in looseness of fastening screws owing

to shrinkage of insulation washers, or electrostatic discharge (ESD), which may
damage the CMOS circuit on the router.

 A high temperature will speed up the aging of insulation materials, which greatly

lowers the router’s reliability and shortens the service life.

Table 2-1 lists the requirements on temperature and humidity for the A6602.

Table 2-1 Temperature and humidity requirements in the equipment room

Temperature Relative humidity

0°C to 45°C (32°F to 113°F) 10% to 95% (noncondensing)

Cleanness Requirements

Concentration limit of dust

Dust is harmful to the safe operation of the router. Dust on the chassis may result in static
adsorption, which causes poor contact between metal connectors or joints. The poor contact
may not only shorten the service life of the router, but also bring about communication
failures. Especially under the condition of low indoor humidity, dust is more likely to occur,
causing static adsorption.

Table 2-2 lists the requirements on the dust concentration and diameters in the equipment

room.

Ventilation Requirements

The fans of the A6602 draw air in through the inlet vents on the left and out through the
exhaust vents on the right.

Figure 2-1 Ventilation method for the A6602

Make sure that:

 There is a minimum clearance of 10 cm (3.9 in) around the inlet vents and exhaust

vents for heat dissipation of the router chassis.

 A ventilation system is available at the installation site.

Electrostatic Discharge Prevention

Generation and damage of static electricity

In the communication network to which the router is connected, static induction mainly
results from:

 External electrical fields such as outdoor high voltage power line or lightning
 Indoor environment, flooring materials, and the router structure

Although many antistatic considerations have been given to the A6602, damage to board
circuits or even the router may still happen when the static electricity exceeds a certain limit.

Measures against ESD

To prevent electrostatic discharge (ESD),

 Make sure that the router and the floor are well grounded.
 Take dust-proof measures for the equipment room.
 Maintain the humidity and temperature at a proper level, respectively.
 Wear an ESD-preventive wrist strap when touching a circuit board or optical

interface module.

 Place the removed memory module, CF card, or HIM/MIM on an antistatic

workbench, with the face upward, or put it into an antistatic bag.

 Touch only the edges, instead of electronic components when observing or moving

a removed memory module, CF card, or HIM/MIM.

Connection of the ESD-preventive wrist strap

Follow these steps to connect the ESD-preventive wrist strap:

Step1 Put on the ESD-preventive wrist strap, ensuring the strap makes good skin
contact.

Step2 Attach the alligator clip to the rack.
Step3 Make sure that the rack is well grounded.

Figure 2-2 Connect the ESD-preventive wrist strap

(1) ESD-preventive wrist strap (2) Snap fastener
(3) Alligator clip (4) Rack

 For the sake of safety, check the resistance of the ESD-preventive wrist strap. The

resistance reading should be in the range of 1 to 10 megohms between human body and
the ground.

 The ESD-preventive wrist strap is user-supplied.

Electromagnetic Interference Prevention

All possible interference sources, external or internal, affect the router in the way of
capacitance coupling, inductance coupling, electromagnetic radiation, and common
impedance (including the grounding system) coupling. To minimize the influence of
interference sources on the router, you should take the following into consideration:

 Take effective measures to protect the power system from the power grid system.
 Separate the protection ground of the router from the grounding device or lightning

protection grounding device of the power supply equipment as far as possible.

 Keep the router far away from radio stations, radar, and high-frequency devices

working in high current.

 Use electromagnetic shielding when necessary.

Lightning Protection

Although many measures have been taken to protect the A6602 from lightning, if the lightning
intensity exceeds a certain range, damage to the router may still happen. To protect the router
from lightning better, you are recommended to do as follows:

 Ensure the PGND cable of the chassis is well grounded.
 Ensure the grounding terminal of the AC power socket is well grounded.
 Install a lightning arrester at the input end of the power supply to enhance the

lightning protection capability of the power supply.

 Install a special lightning arrester at the input end of outdoor signal lines (for

example, E1/T1 line) to which interface modules of the router are connected to
enhance the lightning protection capability.

Refer to Chapter 3 “Installing the Router” for the connection of the PGND cable and the
installation of the power lightning arrester and signal lightning arrester.

PGND Cable Connection

Importance of the PGND Cable

The correct connection of the protection ground (PGND) cable on the router chassis is an
essential safeguard against the lightning strokes and EMI. You need to correctly connect the
PGND cable when installing or using the router.

The AC power input end of the A6602 is equipped with a noise filter. The neutral ground of the
power input end is directly connected to the chassis and is called PGND (also known as chassis
ground). You need to securely connect the PGND cable to the earth ground to safely lead
induced current and leakage current to the ground and reduce the EMS of the router. The
PGND cable can also protect the router against high lightning voltage resulting from external
network lines such as E1/T1.

Connecting the PGND Cable

Generally, you need to connect a signal lightning arrester (namely, a transient over-voltage
protection) before connecting a signal cable to the router. This can protect electronic devices
against surge over-voltage resulting from lightning strokes and other interferences, and
minimize impact on the router.

Because the signal lightning arrester is serially connected to a signal cable, the signal lightning
arrester must satisfy the requirements of network performance indexes such as data
transmission bandwidth, as well as the lightning protection performance requirement.
Therefore, before installing a signal lightning arrester, you need to consider such performance
indexes of the lightning arrester as lightning protection, bandwidth, transmission loss, and port
type.

The A6602 supports three types of signal lightning arresters:

 Voltage-limiting protection – signal lightning arrester – maximum discharge current

2.5KA/protection voltage 25V--SMB-75J/ SMB-75J-1W-10Mbps

 Voltage-limiting protection – signal lightning arrester – maximum discharge current

2.5KA/protection voltage 25V-BNC-75K/ BNC-75K-10Mbps

 Voltage-limiting protection – signal lightning arrester (U port) - maximum discharge

current 3KA/common-mode 400V/differential mode 170V-RJ11

 The signal lightning arrester should be grounded as near as possible. The grounding

resistance must be less than 4 ohms. The grounding resistance must be less than 1 ohm if
there are special grounding requirements.

 Connect the grounding cable to the special-purpose grounding cable of the signal lightning

arrester and connect it to the earthing network, instead of connecting it to the lightning rod
or lightning belt.

Connecting the Power Cables

Connecting Port Cables

Connecting the Console Cable

Follow these steps to connect the console cable:

Step1 Select a configuration terminal.

The configuration terminal can be a standard ASCII terminal with an RS232 serial port, or a
common PC.

Step2 Connect the console cable.

Disconnect the power supply to the router. Connect the RJ-45 connector of the console cable
to the console port on the router, and the DB-9 (female) connector to the serial port on the
configuration terminal.

Step3 Power on the router after verifying the connection.

Verify the connection and power on the router. The configuration terminal displays the startup
banner of the router if the connection is correct. For details, refer to “Router Power-on” in
Chapter 4 “Starting and Configuring the Router”.

Verifying Installation

Each time you power on the router during installation, you must verify that:

 There is enough space around the router for heat-dissipation and the workbench is

stable enough.

 The power supply matches the requirements of the router.
 The PGND cable of the router is correctly connected.
 The router is correctly connected to the configuration terminal and other devices.

It is very important to verify the installation because the stability and grounding of the router and
the power supply will directly affect the operation of the router.

Configuration Fundamentals

In general, the configuration steps are as follows:

Step1 Before configuring the router, you should summarize the networking requirements, including

the networking objective, role of the router in the network, division of subnets, WAN type and
transmission medium, network security policy and network reliability.

Step2 Based on the above requirements, draw a clear, complete network diagram.
Step3 Configure the WAN interface of the router. First, configure the physical operating parameters

(for example, the operating mode, baud rate and synchronous clock in the case of a serial
interface) of the interface according to the transmission medium of the WAN. Then, configure
the data link layer protocol encapsulated on the interface and related operating parameters.

Step4 Configure the IP addresses of all the interfaces on the router according to the division of the

subnets.

Step5 Configure routes. If it is necessary to enable a dynamic routing protocol, you need to configure

related operating parameters of the protocol.

Step6 Perform security configuration for the router if necessary.
Step7 Perform reliability configuration for the router if necessary.

For the configuration details of the protocols or functions of the router, refer to HP SR6600
Routers User Manual.

Command Line Interface

Features of the Command Line Interface

The command line interface (CLI) of the A6602 provides a number of configuration commands,
which enable you to configure and manage the router.

The CLI provides the following functions:

 Allows you to perform local configuration through the console port.
 Allows you to perform the local or remote configuration and directly log in to and manage other

routers by using the telnet command.

 Provides online help, which is available by entering “?”.
 Provides network diagnostic tools, such as Tracert and Ping, for quick diagnosis of network

connectivity.

 Provides all kinds of detailed debugging information to help diagnose network faults.
 Supports the auto-complete function. If you enter a conflict-free part of a command, the

command will be interpreted. For example, you just need to enter dis for the display command.

 Supports the suggest function. For example, if you type dis and press Tab , all the commands

started with “dis” will be displayed.

Command Line Interface

The command line interface of the A6602 provides plenty of configuration commands. All the
commands are grouped in system view. Each group corresponds to a view. You can switch
between different configuration views by using the corresponding commands. In general, only
certain commands can be executed in a particular view. However, some commonly used
commands, such as ping and display current-configuration, can be executed in any view.

5 Maintaining Software

Software Components and Functions

Files

Three types of files need to be managed on the A6602. They are:

 BootWare program file
 Application file
 Configuration file

BootWare Program File

The BootWare program file is used for booting the application when the router starts, and is
stored in the flash memory.

The entire BootWare program consists of a basic section and extended section.

 The basic section is used for the basic initialization of the system.
 The extended section provides abundant human-computer interaction (HCI) functions and is

used to initialize interfaces and update the applications and the boot system.

 After the basic section is loaded, you can load and update the extended section through the

menu of the basic section.

Application Files

The A6602 supports the Dual Image function. By default, the system defines three types of
application files for boot.

 Main application file (with the attribute of M)
 Backup application file (with the attribute of B)
 Secure application file (with the attribute of S)

These three types of application files are stored in a CF card. By default, they are written into
the built-in CF card before delivery.

If you have uploaded all the three types of application files into the built-in CF card, the system
will boot using these three files in order. For more information about application files, refer to
"Maintaining Application and Configuration Files” on page 5-27.

The following gives the default names and types of the application files and their priorities for
system boot.

 Main application file. The default name is main.bin. It is the default application file used for

system boot.

 Backup application file. The default name is backup.bin. When booting with the main

application file fails, the system boots using the backup application file.

 Secure application file. The default name is secure.bin. When booting with the main and

backup application files fails, the system boots using the secure application file. If booting with
the secure application file fails, the system prompts a boot failure.

Note that:

 An application file with the attribute of M, B, or S can be used to boot the system, but one with

an attribute denoted by N/A (that is, an application file without a specific attribute assigned to it)
cannot.

 You can modify the name of an application file using a command after the application boots.

 You can modify the attribute of application files on the BootWare menu or at the command line

interface (CLI) after the application is started.

 As the secure application file is the last resort for system boot, you cannot change its attribute,

or turn another type of application file into a secure application file by means of attribute
modification. You can only download it on the BootWare menu.

 Only one apllication file of the same type (M, B, or S) can exist in the CF card. For instance, if

an application file in the CF card has both M and B attributes, no other applcation file with the
attribute of M or B can exist in the CF card. If the attribute of another application file is changed
from N/A to B, the existing file that has both M and B attributes will lose its B attribute.

Configuration Files

The configuration files are used to store the configuration information of the router and load the
configuration information at system boot. The system supports the main and backup attributes
of configuration files, it defines three types of configuration files by default:

 Main configuration file (with the attribute of M)
 Backup configuration file (with the attribute of B)
 Default configuration file (with the attribute of S)

The main and backup configuration files are used as follows:

 If the main configuration file is damaged or lost, the backup configuration file is used for loading

the configuration information. This double protection mechanism enhances the reliability of the
file system.

 When saving the current configuration, you can specify to save it to the main configuration file,

the backup configuration file, or a configuration file with the attribute denoted by N/A, namely a
configuration file without a specific attribute assigned to it.

 When deleting a configuration file, you can specify to delete the main or backup configuration

file. For a configuration file with both M and B attributes, you can specify its M or B attribute to
remove.

 You can define a configuration file as the one to be used at the next boot by changing its

attribute to M.
The secure configuration file is used when the system fails to boot using the main, and then the

backup configuration file. Currently the system does not support boot with the secure
configuration file.

The system will select the configuration files in order to load configuration information at startup:

 Uses the main configuration file to initialize the configuration if the main file exists.
 Uses the backup configuration file to initialize the configuration if the main file does not exist.
 Boots using the null configuration (default settings) if the backup file does not exist either.

For more information about configuration files, refer to “Setting the Application File Attributes“
on page 5-28.

Note that:

 You can rename a configuration file through the CLI after the application program is loaded.
 You can modify file attributes on the BootWare menu or at the CLI after the application program

is loaded. For detailed information, refer to “Setting the Application File Attributes“ on page 5-

28.

 A configuration file can have both M and B attributes; but there is only one file of the same

attribute on the device at a time.

 The configuration file name containing a drive identifier and a string terminator cannot be longer

than 64 characters. If the drive identifier is “cfa0:/”, the file name without drive identifier and
string terminator can be at most [ 64 – 1 – 6 ] = 57 characters in length.

 If the file name without drive identifier and string terminator contains more than 57 characters,

errors will occur in file operation. Typically, the file name without drive identifier and string
terminator is recommended to contain no more than 16 characters.

 At BootWare boot, the names of the configuration files will be displayed, but the types will still

be displayed as N/A.

 For details about the startup saved-configuration cfgfile command, refer to HP SR6600

Routers User Manual.

Software Maintenance Methods

You can maintain software of the A6602 in the following two methods:

 Update BootWare and applications using the Xmodem protocol through a serial interface.
 Update applications using FTP/TFTP through an Ethernet interface on the BootWare menu or

at the CLI.
Note that:

 When updating the application file, if you select to overwrite the existing application file, make

sure to secure the power supply during this process; any power failure during this process will
cause application update to fail and will damage the existing application file. In this case, if there
was only one application file for booting the system, the device will be unable to start normally.

 When updating the basic BootWare section, make sure to secure power supply during this

process; any power failure during this process will damage the basic BootWare section,
resulting in failure of device startup.

 When updating the extended BootWare section, you only update part of the BootWare

program. Once an error occurs, you can retry updating the extended BootWare section.

 The BootWare program is updated together with the Comware application. You do not need to

update the BootWare separately. After you update the Comware application to the latest version
and restart the device, the system checks whether the current BootWare version is consistent
with the one in the host application. If not, the system automatically updates the BootWare
program.

 Check the current versions of the BootWare and the Comware application before updating

them. For the association between the Comware application version and the BootWare program
version, refer to the hardware and software compatibility matrix in Release Notes.

Updating an Application and BootWare Through a Serial
Interface

Introduction to Xmodem

Use Xmodem when updating an application and BootWare through a serial interface.
Xmodem is a file transfer protocol that is widely used due to its simplicity and high performance.

Xmodem transfers files through a serial interface. It supports two types of data packets (128
bytes and 1 KB), two check methods (checksum and CRC), and error packet retransmission
mechanism (generally the maximum number of retransmission attempts is 10).

The XMODEM transmission procedure is completed by the cooperation of a receiving program
and a sending program. The receiving program sends a negotiation character to negotiate a
packet check method. After the negotiation, the sending program starts to transmit data
packets. When receiving a complete packet, the receiving program checks the packet using the
agreed method.

 If the check succeeds, the receiving program sends an acknowledgement character and the

sending program proceeds to send another packet.

 If the check fails, the receiving program sends a negative acknowledgement character and the

sending program retransmits the packet.

Modifying Serial Interface Parameters

In actual applications, you need to make the serial interface baud rate higher to save updating
time or make it lower to guarantee transmission reliability. This section introduces how to adjust
the serial interface baud rate.

Enter the main menu and select 2 to enter the serial interface sub-menu, and then select 5 from
the sub-menu to modify the baud rate. The system displays the following:

========================<BAUDRATE SET>====================================
|Note:'*'indicates the current baudrate |
| Change The HyperTerminal's Baudrate Accordingly |
|--------------------<Baudrate Available>------------------ -|
| <1> 9600(Default) * |
| <2> 19200 |
| <3> 38400 |
| <4> 57600 |
| <5> 115200 |
| <0> Exit |

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

Enter your Choice(0-5):

Select a proper baud rate. For example, select 5 for a baud rate of 115200 bps and the system
displays the following information:

Baudrate has been changed to 115200 bps.
Please change the terminal's baudrate to 115200 bps, press ENTER when ready.

At this time, the baud rate of the serial interface of the router is modified to 115200 bps, while
that of the terminal is still 9600 bps. The router and the terminal cannot communicate with each
other. Therefore, you need to make the baud rate on the terminal consistent with that on the
router.

Perform the following operations on the terminal:

Figure 5-2 Disconnect the terminal

Step1 Select File > Properties, and then click Configure… to change the bits per second to 115200.

Figure 5-3 Modify the baud rate on the terminal

Step2 Select Call > Call to establish a new connection.

Figure 5-4 Re-establish a call connection

Then, press the Enter key, and the system will prompt the current baud rate and return to the
previous menu.

The system displays:

The current baudrate is 115200 bps

After you download files to update applications by changing the baud rate, restore the baud rate
in the HyperTerminal to 9600 bps in time, so as to ensure the normal display on the console
screen when the system boots or reboots.

Updating an Application

The application updating through a serial interface is implemented on the serial sub-menu.
Select 2 from the main menu to enter the serial sub-menu. For detailed description on this sub-

menu, refer to “Serial Sub-menu” on page 5-7.
The following example shows how to update the main application file main.bin:
To improve the updating speed, you can modify the serial port baud rate before updating the

main application file (refer to “Modifying Serial Interface Parameters” on page 5-10). Select 2
from the serial port sub-menu, and the system prompts:

Updating an Ap

plication Using TFTP

When the application file is large, you can update it using TFTP to save update and

maintenance time.

Trivial File Transfer Protocol (TFTP), a protocol in the TCP/IP protocol suite, is used for trivial

file transfer between client and

services. TFTP provides unreliable data transfer services over UDP and does not provide any

access authorization and authentication mechanism. It employs timeout and retransmission to

guarantee

successful data delivery.

The A6602

router can serve as the TFTP client. Therefore the file server serves as the TFTP

server. You can upload/download the application file on the router to/from the file server.

There are two approaches to updating applic

 Using the BootWare menu
 Using the CLI.

 The FTP service is enabled after the authentication and authorization of the FTP server are

configured. The FTP server supports multi-client access. A remote FTP client sends a request
to the FTP server. The FTP server executes an action accordingly and returns the execution
result to the client.

 After you configure the FTP server authentication and authorization, you need to set the user

level to 3. Otherwise, the system prompts that “You have no rights to store files” when you
restore the backed-up file to the router. For configurations of user levels, refer to HP SR6600
Routers User Manual.

 When you update an application file, if the file name already exists on the server, the system

overwrites the file on the server directly, without any prompt.

 For details about the put command, refer to HP SR6600 Routers User Manual.
 You can update a configuration file in the way you update an application file. A configuration file

can be modified by a text editor. You can modify a configuration file and then download the
modified configuration file to the router, and the modification takes effect after the router
reboots.

5) Back up an application file.
Using FTP, you can back up an application file by downloading it from the server to the client.
# Download file main.bin from the router to the PC, and save it as main.bin.

ftp> get main.bin main.bin

Setting configuration file attributes at the CLI

You can use the startup saved-configuration cfgfile [ backup | main ] command to define the
configuration file to be used for the next boot and its attribute. In this command, use cfgfile
argument to specify the configuration file name.

Note that:

 You can use the startup saved-configuration cfgfile main command to change the attribute of

an N/A-type configuration file to M.

 You can use the startup saved-configuration cfgfile backup command to change the

attribute of an N/A-type configuration file to B.

 You can use the startup saved-configuration cfgfile backup command to change the

attribute of an M-type configuration file to M + B.

 You can use the startup saved-configuration cfgfile main command to change the attribute of

a B-type configuration file to M + B.

 If you use neither main nor backup in your command, you assign the M attribute to the

specified configuration file.

 If you assign the M attribute to a configuration file, the attribute of the existing main

configuration file, if any, is automatically erased, because there can be only one main
configuration file in the system at a time.

 If you assign the B attribute to a configuration file, the attribute of the existing backup

configuration file, if any, is automatically erased, because there can be only one backup
configuration file in the system at a time.

 You can use the undo startup saved-configuration command to erase the main and backup

attributes of the configuration files. Namely, the system has no longer a main, nor a backup
configuration file after this command.

# Define the file startup.cfg as the backup configuration file for the next system boot.

The above information indicates that the password authentication is adopted on the console
interface and the password is set to 123456 and stored in plain text.

Set the password by using the set authentication password { cipher | simple } password
command.

 If the cipher keyword is specified, the password is stored in cipher text. You cannot view the

password by using the display current-configuration command.

 If the simple keyword is specified, the password is stored in plain text. You can use the

display current-configuration command to view the password in the current configuration.

 After reboot, the system runs with the initial default configuration, but the original configuration

file is still stored in the storage medium. To restore the original configuration, you can use the
display saved-configuration command to display the configuration, and then copy and
execute the configuration.

 If the password is stored in plain text, you can use the display current-configuration

command to view the password in the current configuration. If the password 123456 is set with
the set authentication password cipher command, the password is stored in cipher text.

4) Save the new password.

[HP] save

 Execute the save command after modifying the user password to save the new password.

7 Troubleshooting

 The barcode stuck on the router chassis contains information about production and

servicing. Before you return a faulty router for serving, please provide the barcode
information of the router to your local sales agent.

 An HP tamper-proof label is stuck on a mounting screw on the router chassis. The local

sales agent requires intactness of the tamper-proof label when maintaining the router.
Therefore, before you open the chassis cover, please contact your local sales agent to ask
for permission or follow the instruction as provided by the agent; otherwise, the user takes
full responsibility for own operation if any maintenance failure occurs.

Troubleshooting the Power System

Symptom

The router cannot be powered on. The power LED on the front panel is off.

Solution

Follow these steps to troubleshoot the power system:

 Turn off the power switch.
 Remove the chassis cover.
 Check whether the power cord is properly and firmly connected.
 Check whether the power cord is not damaged.

If the cause cannot be located in the steps above and the problem persists, contact your local
sales agent.

Troubleshooting Fans

Symptom

After the router is booted, the following information appears:

%Jun 22 16:11:37:485 2007 HP DEV/4/FAN FAILED:

Fan 1 failed.

Solution

Follow these steps to troubleshoot fans:

 Turn off the power switch.
 Remove the chassis cover.
 Check whether fans are in position.
 Check whether any fan has stopped running. If yes, contact your local sales agent

to have the fan replaced.

If the cause cannot be located in the steps above and the problem persists, contact your local
sales agent.

Troubleshooting the Configuration System

If the system runs normally after the router is powered on, the booting information is
displayed on the configuration terminal. If the configuration system is faulty, the terminal
screen may display nothing or illegible characters.

No Display on the Terminal Screen

Symptom

After the router is powered on, the configuration terminal displays nothing.

Solution

Check that:

 The power supply is normal.
 The console cable is properly connected.

If the cause cannot be located in the steps above, the possible reasons are as follows:

 The serial port to which the console cable is connected is not the one configured in

the emulation program.

 Terminal settings are incorrect. The required settings are as follows: 9600 bits per

second, 8 data bits, 1 stop bit, no flow control, and VT100 for terminal emulation
type.

 The configuration cable is not in good condition.

Illegible Characters on the Terminal Screen

Symptom

After the router is powered on, the configuration terminal displays illegible characters.

Solution

 If the “Data bits” field is set to 5 or 6 in the emulation program, illegible characters

appear on the screen. Set this field to the default value 8.

 Make sure that the work mode of the AUX port is flow when using the AUX port as

the backup console port. For more information, refer to “Using the AUX Port as

Backup Console Port” on page 7-3.

Serial Port Response Failure

Symptom

The serial port gives no response.

Solution

Check that the cable is in good condition and the serial port settings are correct.

For more information about serial port settings, refer to “Modifying Serial Interface Parameters”
in Chapter 5 “Maintaining Software”.

Using the AUX Port as Backup Console Port

Symptom

When the console port is faulty, you can use the AUX port as the backup console port to
complete router configuration.

Solution

 Make sure that the work mode of the AUX port is flow.
 Power off the router, connect the RJ-45 connector of the console cable to the AUX

port, and then connect the DB-9 (female) connector to the serial port of the
configuration terminal.

 Power on the router.

 The AUX port can only be used normally after user level and password are configured.
 The AUX port can work in the flow or protocol mode. The AUX port can be used as the

backup console port only when it works in the flow mode.

 The AUX port works in the flow mode by default.
 Use the async mode { flow | protocol } command to switch between the flow mode and

the protocol mode. For more information, refer to HP SR6600 Routers User Manual.

Password Loss

If you have lost the BootWare password, user password, or super password, refer to “Dealing
With Password Loss” in Chapter 5 “Maintaining Software”.

Troubleshooting the Cooling System

Symptom

The temperature inside the router exceeds 45°C (113°F).

Solution

 Check whether the fans are running normally.
 Check whether the working environment of the router is well ventilated.
 If the temperature inside the router exceeds 75°C (167°F), the following information

appears on the configuration terminal:

%Jun 28 10:27:27:653 2007 HP DRVMSG/3/Temp2High:

Environment temperature too high in Slot 0, index is 1.

#Jun 28 10:27:28:432 2007 HP DEV/1/BOARD TEMPERATURE UPPER:
