Chapter 1 Router Overview
1.1 Introduction
H3C AR 46 Series Routers are next generation high-performance edge routers that
H3C Technology solely developed. They provide high forwarding performance and a
broad service range. The series supports flexible interface cards (FICs), hot swappable
fan modules and power supply units (PSUs) in 1+1 redundancy. Along with the NE
Series Routers, the AR 46 series provides complete network solutions for service
providers and enterprises.
The following are the major features of the AR 46 series.
I. Abundant FIC options
The H3C AR 46 series are available with a wide range of FICs. This allows for great
flexibility and thus protects user investment.
II. Ethernet access
The electrical and fiber (multi-mode and single-mode) Ethernet FICs support PPPoE
and PPPoEoA, and can offer authentication, authorization, and accounting (AAA)
services for Ethernet access. These cards are suitable for providing broadband access,
for example, for government agencies and enterprises.
III. ATM and DSL
Digital subscriber line (DSL) is a simple but highly efficient broadband technology which
achieves great data transmission capacity over existing copper wiring by using the
digital code modulation technology. Installed with an ADSL or G.HSDSL card, the AR 46
series can connect medium-to-small-sized enterprises to digital subscriber line access
multiplexer (DSLAM) equipment across a public switched telephone network (PSTN) to
the Internet.
Asynchronous transfer mode (ATM) transmits, multiplexes, and switches information in
cells. In addition to DSL cards, the AR 46 series is available with these ATM cards: 25
Mbps, 155 Mbps, E3/T3, and IMA-E1/T1. The cards support ATM adaptation layer type
5 (AAL5) and offer traffic services such as constant bit rate (CBR), variable bit rate
(VBR) and unspecified bit rate (UBR). They are well-suited to transfer large packets
and provide high-speed data services. A small to medium-sized enterprise can use
them to connect its network to an ATM network.
IV. MPLS
Multiprotocol label switching (MPLS), a combination of IP and ATM technologies,
replaces the IP header with a short and length-fixed label as traffic identifier, based on
Page 9
H3C AR 46 Series Routers Installation Manual Chapter 1 Router Overview
1-2
which each router makes forwarding decision. It thus provides faster forwarding speed,
gets support from IP routing and control protocols, and accommodates to emerging
applications. In an MPLS network, labeled packets are transmitted along a label
switched path (LSP) formed by label switching routers. As an LSP is virtually a tunnel
across the public network, MPLS has an intrinsic advantage in terms of VPN
implementation. The AR 46 series usually acts as label edge routers (LERs) to connect
an MPLS domain with a non-MPLS domain or connect MPLS domains of different
service providers, implementing service classification, label distribution, encapsulation,
and multi-label peel-off.
V. Data security and reliability
The following are the data security and reliability features that the AR 46 series
supports:
z NAT. Besides some basic functions, NAT can limit concurrent connections to a
single user, and thus alleviate negative impact caused by malicious resources
occupation without affecting the normal network applications. In addition, NAT of
the AR 46 series also provides the application layer gateway (ALG) function
specific to FTP and ICMP.
z Identity authentication protocols such as PAP, CHAP, data RADIUS, VoIP
RADIUS, and TACACS.
z Packet filter and application specific packet filter (ASPF), which fend off external
attacks.
z VPN (including GRE, L2TP, DVPN, and MPLS L2/L3 VPN) and the technologies
of IPSec and IKE. They can ensure security of private networks in an Internet
environment.
z Backup center and virtual router redundancy protocol (VRRP). By providing a
backup scheme in case of communication line or device failures, they enhance
robustness and reliability of networks. Backup center also supports backup load
sharing.
z Hot swappable fans, interface cards, and PSUs to ensure high reliability.
VI. Online software upgrading
You are allowed to upgrade application and Boot ROM programs, and add new
features and functions on line as needed.
VII. Abundant fault isolation methods
z You are available with the means to monitor the states of system configurations,
system service channels, and system resources, as well as fault indication via
console and network management host. In addition, logging function is provided
for recording and outputting the abnormal information.
z You are allowed to monitor the FIC running state and make the judgment by
observing the LEDs on FIC panels.
Page 10
H3C AR 46 Series Routers Installation Manual Chapter 1 Router Overview
1-3
z You are also provided with the functions of in-service system test, out-of-service
system test. In addition, loopback test and hardware key module self-test are
allowed.
VIII. Regulatory compliance
The AR 46 Series Routers are designed in compliance with the regulations and
standards of China, North America, Europe, Europe, Australia, and Japan in EMC,
safety, network access, and some other aspects.

The ERPU provides three 10/100/1000 Mbps Ethernet interfaces that each
accommodate an RJ-45 connector and a small form-factor pluggable (SFP) module
respectively for electrical and optical connections. But you can use only one connection
at a time.
Five types of 1000Base-FX SFP transceiver modules are available: multi-mode
short-haul (850 nm), single mode medium-haul (1310 nm), single mode long-haul
(1310 nm), single mode long-haul (1550 nm), and single mode ultra-long haul (1550
nm). They all provide LC interfaces and are hot swappable.

Caution:
Data loss occurs when a CF card is plugged or unplugged during a read or write
operation.
IV. Encryption daughter card
An encryption daughter card can be installed on the ERPU. It supports IPSec and by
using hardware encryption expedites IP packet encryption. The use of hardware
encryption/decryption and hashing operation allows the router to encrypt packets with
high performance and reliability. In addition, the card supports DVPN.
The encryption daughter card is optional. On a router installed with an encryption card,
the main control board functions to route IP packets and implement encryption-enabled
VPN, while the encryption daughter card functions to encrypt packets.

1.4.4 PSU
I. Functions
The power supply system of the H3C AR 46 series can work in either single-power or
dual-power mode. In dual-power mode, the two PSUs (DC-input or AC-input) function
in redundancy or load sharing mode. That means, when a PSU fails or its power supply
is disconnected, another PSU can still work and supply all the power required by the
system.
Both AC-input PSU and DC-input PSU are available with the H3C AR 46 series. The
PSUs supply 350W power and provide overcurrent and overvoltage protection.
You can connect a PSU to the backplane by inserting it from the rear of the router
chassis. It is hot swappable and its switchover does not affect the ongoing system
operation.
Note:
When installing your router in a communications equipment room, ensure that the AC
power distribution cabinet can provide a lightning protection box or arrester against the
current of 20 KA and above.

1.4.5 FAN module
I. Functions
The AR 46-20 and the AR 46-40 are configured with six fans; the AR 46-80 is
configured with eight fans. These fans are working in pairs and the two fans in each pair
are working in redundancy. When all these fans are working normally, the operating
temperature of the system can be maintained between 0 and 55°C (32 to 131°F). As
the failure of a fan does not affect the operation of other fans, the normal operating
temperature of the system can maintain.
Page 26
H3C AR 46 Series Routers Installation Manual Chapter 1 Router Overview
1-19
The routing speed of the fans is adjusted by the fan controller on the main control board
and between 50% and 100% depending on the system temperature. When the system
temperature rises above the high-temperature threshold set by the fan controller, the
fans are rotating at full speed (100%); when the system temperature drops below the
low-temperature threshold, the fans are rotating only at half of the speed (50%). When
a fan stops rotating, the fan controller alarms.
The alarm and state LEDs of the FAN are located on the front panel of RPU or ERPU.

Chapter 2 Preparing for Installation
2.1 General Site Requirements
The AR 46 series must be used indoors. To guarantee normal operation and longevity
of your device, its installation site should meet the requirements described in this
chapter.
2.1.1 Temperature and Humidity
The equipment room must maintain proper humidity to prevent poor insulation,
electricity creepage and corrosion accompanying high humidity, or washer contraction
and electrostatic discharge accompanying low humidity. In dry environments where the
relative humidity is very low, electrostatic discharge (ESD) is more likely to happen
causing the complementary metal-oxide-semiconductor (CMOS) circuitry to fail.
A proper temperature condition must be maintained also to prevent premature material
aging and degraded reliability accompanying high temperature conditions.
The following table lists the temperature and humidity requirements.
Table 2-1 Temperature/humidity requirements in the equipment room
Temperature Relative humidity
0°C to 40°C (32°F to 104°F) 5% to 90%
2.1.2 Cleanness
Dust is hazardous to the operating safety of your device. Dust buildup on the chassis
may result in static absorption, causing poor contact of metal components or points.
When indoor humidity is extremely low, this is more likely to happen to shorten the
useful life of the device and cause communication failures.
The equipment room must be free of explosion hazards and the electrical and magnetic
conductible dust as well. The following table lists the limits on dust particles:

(No visible dust on desk in three days)
Note: Dust particles’ diameter ≥ 5µm
Besides, the equipment room should meet the rigorous limits on salt, acid and sulfide to
eliminate corrosion and premature aging of some parts, as shown in the following table.

2.1.3 ESD Prevention
By design, the router is ESD preventative; but excessive buildup of static electricity can
still damage the card circuitry and even the entire device.
On the communication network connected to the router, static electricity is primarily
introduced from the outside electrical fields, such as the outdoor high-voltage power
cabling and lightning, and from the inside system, such as indoor environment, floor
material and the equipment frame. To avoid damage, ensure that:
z The equipment is well connected to earth.
z The equipment room is dust-proof.
z Maintain adequate temperature and humidity.
z Wear an ESD-preventive wrist strap and clothes when contacting the circuit board.
z Place the removed circuit board upward on the ESD-preventive workbench, or into
a static shielded bag.
z Hold the circuit board by its edge when observing or moving it, avoiding direct
contact with the elements on it.
2.1.4 Electromagnetic Compatibility
All interference sources, from the outside or from the inside of the router/application
system, adversely affect the router in the conduction patterns of capacitance coupling,
Page 33
H3C AR 46 Series Routers Installation Manual Chapter 2 Preparing for Installation
2-3
inductance coupling, electromagnetic wave radiation, and common impedance
(including grounding system) coupling. To prevent the interference, do the following:
z Take effective measures against interference from the power grid.
z Use an earthing system or lightning protection grounding different from that for the
power supply equipment and keep them as far as possible.
z Keep the router far away from strong power wireless launchers, radar launchers
and high frequency and high-current equipment.
z Use electromagnetic shielding when necessary.
2.1.5 Lightning Protection
By design, the router is lightning protective; but excessive lightning may still damage
the device. To protect the device better, you are recommended to:
z Ensure the PGND of the chassis is securely connected to the earth ground.
z Ensure the earth point of the power socket is securely connected to the earth
ground.
z Add a lightning arrester onto the front end of the power input to better protect the
power supply from lightning strikes.
z For signal cables such as ISDN cables, telephone cables, E1/T1 cables, install a
special lightning arrester at their input end for better protection.
2.1.6 Checking the Rack
When installing the router, observe the following:
z Reserve adequate clearance at the air intake exhausting vents for adequate
ventilation inside the chassis.
z Make sure that the rack has a good ventilation system.
z Make sure that the rack is sturdy enough to support the weight of the device and
the installation accessories.
z Make sure that the rack is well-grounded.
2.2 Safety Precautions
When reading this manual, pay adequate attention to the following.
Warning appears in operation procedures that, if performed incorrectly, might
cause bodily injury to the operators or damage the device.
Caution appears throughout this manual in procedures that, if performed
incorrectly, might affect the operation of the router.
When installing or working on the router, you are recommended to:
z Keep the router far away from the heat sources and water/liquid.
Page 34

z The requirements described in the chapter “Preparing for Installation” have been
met.
3.2 Installing the Cabinet/Rack
H3C B68 cabinets are available for mounting the AR 46 Series Routers. For more
information on the cabinets and their installation, refer to the appendix “Installing the
B68 Cabinet”.
Skip this section if you want to mount your router on the tabletop or the rack of another
vendor.
3.3 Mounting the Router
3.3.1 Rack-Mounting the Router
The AR 46 Series Routers are designed to fit standard 19-inch racks. The following
table describes their dimensions.
Table 3-1 Dimensions of the AR 46 series routers
Model Dimensions
AR 46-20 (H × W × D)
130.5 × 436.2 × 420 mm (5.1 × 17.2 × 16.5 in.)
AR 46-40 (H × W × D) 130.5 × 436.2 × 420 mm (5.1 × 17.2 × 16.5 in.)
AR 46-80 (H × W × D) 219.5 × 436.2 × 420 mm (8.6 × 17.2 × 16.5 in.)
Take these steps to mount the chassis:
1) Check that:
z The rack is well fixed.
z The rack is ready for installation without debris inside or around. The chassis is
near to the rack.
2) Attach the mounting brackets onto both sides of the chassis with a Phillips
screwdriver. Note that the mounting brackets are installed with
cable-management brackets. Skip this step, if you mount the router on a tabletop.
Figure 3-2 shows mounting brackets on the AR 46-20/AR 46-40 routers. As sho wn
in the figure, there are two rows of five holes on one side of the mounting brackets.
You can use three holes in either row to mount the brackets on the chassis. Thus,
Page 38

the distance between the interface card and cabinet door is adjustable, in order to
avoid the situation that the door cannot be closed due to the cables coming out of
the interface card.
Figure 3-2 Mounting brackets on the AR 46-20/AR 46-40 routers
3) Lift the chassis a little higher than the shelf or guides in the rack, put it on the
shelf/guides, and push it into the rack. Note that the AR 46-80 might require two
persons to lift it.
4) Securely fix the chassis in the rack by fixing the mounting brackets with the proper
pan head screws onto the front posts or back posts. Skip this step, if you do not
use a rack.

3.3.2 Mounting the Router on a Tabletop
When mounting the router on a tabletop, ensure that the surface is clean and you have
considered the following:
z The table is sturdy and well grounded.
z 10 cm (3.9 in.) of clearance is available around the sides of the chassis for heat
dissipation.
z Do not place any heavy object on the chassis.
3.4 Installing the Generic Modules
Installing generic modules includes installing the main control board, PSUs, the fan
module, and FICs.
For more information about FICs and their inst allation, refer to Low-End and Mid-Range
Series Routers Interface Card and Interface Module Manual.
3.5 Connecting the PGND
Warning:
The normal connection of the protection ground (PGND) on the router chassis is an
essential safeguard against the lightning shocks and interference. You must correctly
connect the PGND when installing or using the router.
As shown in the following figure, the router provides a protection ground (PGND) screw
at the top right-rear of the chassis. You must securely connect it to the earth ground to
safely channel faradic current and leakage electricity to the ground and have the device
less susceptible to electromagnetic interference (EMI). The PGND also protects the
system against high voltage of lightning shocks caused by external network lines like
E1/T1 and ISDN/PSTN lines.

Connect the PGND to the earth ground using a PGND cable with a grounding
resistance less than 5-ohm. If you install the chassis in a 19-inch standard rack, you
must also ground the rack.
Warning:
Lightning strikes can damage your router and even the connecte d devices. For se cure
lightning protection, make sure that your router has a good ground connection when it
is operating.
3.6 Connecting the Power Cord
The AR 46 series is available with both AC-powered and DC-powered units. Except for
PSU type, they have the same features and functions.

Figure 3-8 Console cable
III. Connecting the console cable
Follow these steps to connect the router to a console terminal:
Step 1: Select a console terminal. It can be a standard ASCII terminal with an RS232
serial port, or more commonly, a PC.
Step 2: Power down the ro uter and the console terminal; con nect the RS232 seri al port
on the console terminal to the console port on the router through the console cable.
Step 3: Verify the connection and power up the devices.
Page 43
H3C AR 46 Series Routers Installation Manual Chapter 3 Installing the Route
r
3-8
The console terminal shows the startup information of the router if the connection is
correct. For details, see the chapter “Starting and Configuring the Router”.
3.8 Connecting the Router to a LAN
I. Ethernet interface
The RPU provides two 100Base-TX FE interfaces. For their attributes, refer to the
section “RPU”.
The ERPU provides three 10/100/1000 Mbps auto-sensing Ethernet interfaces that
each accommodate an RJ-45 connector and an SFP module respectively for elect rical
and optical connections.
The ERPU(H) provides three 10/100/1000 Mbps Ethernet interfaces, where two are
electrical and one provides both fiber-optic and electrical connectors.
When both electrical and optical connections are available, you can use only one at a
time. For the available SFP options and the interface attributes, refer back to the
section “ERPU“ in the chapter “Router Overview”.
II. Ethernet cable
1) Electrical Ethernet interface cable
Electrical Ethernet interfaces usually use category 5 twisted-pair cables, as shown in
the following figure.
Figure 3-9 Ethernet cable
Ethernet cables fit into the following two categories:
z Straight-through cable, at both ends of which, wires are crimped in the RJ-45
connectors in the same sequence. The cable connects different types of devices,
such as a terminal device (PC for example) or router to a Hub or LAN switch. The
network cables shipped with the router are straight-through cables.
z Crossover cable, at both ends of which, wires are crimped in the RJ-45 connectors
in different sequences. The cable connects the same type of devices, such as PC
to PC or PC to router. You can make crossover cables by yourself as needed.
Page 44
H3C AR 46 Series Routers Installation Manual Chapter 3 Installing the Route
r
3-9
Note:
In making network cables, shielded cables are preferred for electromagnetic
compatibility sake.
2) Fiber-optic Ethernet interface cable
For the 10/100/1000 Mbps fiber-optic Ethernet interfaces on the ERPU/ERPU(H),
select single mode or multi-mode optical fibers depending on the type of the installed
1000Base-FX SFPs. As the interfaces that these SFP modules provide use LC-type
fiber-optic connectors, you must use fibers with LC-type connectors for them. All these
SFPs are hot swappable.
Note:
SFPs are optional. They are provided only when ordered.
III. Connecting the Ethernet cable
Note:
The fiber-optic and electrical connections that a 10/100/1000 Mbps Ethernet interface
provides cannot operate at the same time. If both connections are present, the system
considers the electrical interface as the operating interface by default.
1) Connect the electrical Ethernet interface cable
Follow these steps to connect the cable:
Step 1: Connect one e nd of the Ethernet cable to an Ethernet port on the route r and the
other end to another device.
z For a 10/100 Mbps port provided by the RPU, connect it to a PC or another router
using a crossover cable or to a Hub or LAN switch using a strai ght-through cable.
z For a 10/100/1000 Mbps Ethernet port provided by the ERPU/ERPU(H), either
straight-through or crossover cable can be used to con nect to a Hub or LAN switch
because MDI/MDIX autocrossover is supported.
Step 2: V iew the LINK LED of the Ethernet interface: ON means a link is present. OFF
means no link is present; check the line for the cause.
Page 45
H3C AR 46 Series Routers Installation Manual Chapter 3 Installing the Route
r
3-10
2) Connect the fiber-optic Ethernet interface cable
Caution:
In connecting optical fibers, observe the following:
z Do not over-bend the fiber. Its curvature radius must be greater than 10 cm (3.9 in.).
z Ensure that the Tx and Rx ends are correctly connected.
z Ensure that the fiber ends are clean.
Warning:
Laser danger: Invisible laser radiation may be emitted from the fiber-optic ports which
are connected with lasers. To protect your eyes against radiation harm, never stare into
an open fiber-optic port.
Follow these steps to connect a 10/100/1000 Mbps fiber-optic interface on the
ERPU/ERPU(H):
Step 1: Use two fibers to connect the Rx and Tx ends of the interface to another device:
Rx to Tx, and Tx to Rx.
Step 2: Power on the route r and read the LINK LED of the interface: ON mean s the Rx
link is present. OFF means no Rx link is present; check the line for the cause.
3.9 Connecting the Router to a WAN
Many types of WAN interfaces are available with the AR 46 series and the one provided
by the main control boards is AUX interface. The following subsections describe how to
connect it. For connecting the WAN interface on an FIC, refer to Low-End and
Mid-Range Series Routers Interface Card and Interface Module Manual.
I. AUX port
AUX is an RS232 asynchronous serial interface, which can back up a WAN interface
and provide dial connection. In case of console failure, AUX can function as a console
interface. For the AUX interface attributes, refer to the section “RPU”.
II. AUX cable
AUX cable is an eight-wire shielded cable. At one end of the cable is an RJ-45
connector for connecting the console port on the router. At the other end are DB-9
Page 46
H3C AR 46 Series Routers Installation Manual Chapter 3 Installing the Route
r
3-11
(male) connector and DB-25 (male) connector. You can plug either of them into the
serial port on a modem as needed. The following figure illustrates the AUX cable.
Figure 3-10 AUX cable
III. Connecting the AUX cable
Follow these steps to connect the AUX cable.
Step 1: Plug the RJ-45 connector of the cable into the AUX port on the RPU/ERPU.
Step 2: Plug the DB-25 or DB-9 connector into the serial port on the analog modem.
When using the AUX interface for remote configuration or dial backup, you need to
connect the local modem to the remote modem through PSTN and then to the remote
device. For the configuration procedures, refer to Comware V3 Operation Manual.
3.10 Verifying Installation
During router installation, you must verify inst allation each time you power on th e router ,
making sure that:
z Adequate clearance is available around the router sides for dissipation.
z The rack or table is sturdy.
z The power source is correct.
z The PGND on the chassis is securely connected to the earth ground.
z The connections with other devices, such as the console terminal, are correct.
Note:
Secure connection, well grounding, and use of the correct power source are essential
to the normal operation of the router. Make sure that you verify installation as
instructed.

4.2 Router Configuration Basics
4.2.1 Basic Configuration Procedures
The following are the general procedures for configuring the router:
Step 1: Before working on the router, fully comp rehend network requirements, such as
networking purpose, position of the router on the network, subnetting, type of the W AN
and transmission medium, security policy and reliability.
Step 2: Based on the requi rements, draw a clear and complete networking diagram.
Step 3: Configure the WAN interface on the router.
z First, configure the physical operating parameters (such as
synchronous/asynchronous serial interface, baud rate and synchronization clock)
of the interface according to the transmission medium of the WAN. For the dia l-up
interface, you also need to configure DCC parameters.
z Then, configure the link layer protocol and the related operating parameters
according to the type of the WAN.
Step 4: Assign an IP address or IPX network number to each interface on the router
according to subnetting.
Step 5: Configure routing. When enablin g a dynamic routing protocol, you also need to
configure the related operating parameters.
Page 59
H3C AR 46 Series Routers Installation Manual Chapter 4 Starting and Configuring the Route
r
4-12
Step 6: Configure the security settings as needed.
Step 7: Configure the reliability settings as needed.
For more information on the protocols and functions provided by the router, refer to
Comware V3 Operation Manual.
4.2.2 Command Line Interface
I. Characteristics of the command line interface
The command line interface (CLI) available with the H3C AR 46 series provides
commands for configuring and managing the router. It supports:
z Configuring the router locally through the console port.
z Telneting to the router to configure it locally or remotely; telneting from the router
to other routers to manage them.
z Getting online help whenever you want by entering a question mark (?).
z Testing reachability of networks quickly with tools, such as tracert and ping.
z Rich debugging information for network diagnosis.
z The command line interpreter that supports fuzzy keyword search. When inputting
a command, you only need to enter its conflict-free portion, for example, dis for the
display command.
II. Command line interface
The CLI of the H3C AR 46 series provides rich configuration commands. They are
divided in system view into multiple groups, each associated to a view (refer to
Comware V3 Operation Manual). You can switch between different views through
commands. Normally , you can only execute the comma nds appropriate to the view that
you access. However, you can execute in any view some commands in common use,
such as ping, display current-configuration, and interface.
4.2.3 Arranging Slots and Numbering Interfaces
The AR 46 series provides many types of interfaces, such as console, AUX, Ethernet,
serial (synchronous/asynchronous), and asynchronous port. The following describes
how these interfaces are numbered.

2) Interface numbering
The following are interface numbering rules with the AR 46 series:
Page 61
H3C AR 46 Series Routers Installation Manual Chapter 4 Starting and Configuring the Route
r
4-14
z The interfaces are represented by interface-type X/Y/Z, where interface-type can
be serial, asynchronous, ethernet or ATM, and so on; X specifie s the slot numb er;
Y specifies the daughter card number (it is 0 when no daughter card is installed);
and Z specifies the interface sequence number.
z As shown in the above figures, different interfaces on an interface module share
the same slot number X.
z For every interface, Y starts from 0 and Z indicates the interface sequence on the
interface module, from left to right.
If you install an FIC-1FE and an FIC-2FE respectively in SLOT1 and SLOT2 on the AR
46-20, the Ethernet interfaces are numbered as follows:
z Fixed Ethernet interfaces are Ethernet 0/0/0 and Ethernet 0/0/1;
z The Ethernet interface on the FIC-1FE is Ethernet 1/0/0;
z The Ethernet interfaces on the FIC-2FE module are Ethernet 2/0/0 and Ethernet
2/0/1.
The configurations of the interfaces differ by their type. To know how to configure them,
refer to Comware V3 Operation Manual.

Chapter 5 Maintaining Software
5.1 Overview
The router manages three types of files:
z Boot ROM image file
z Application image file
z Configuration file
Software maintenance mainly involves these three types of files. This chapter
discusses only the software maintenance functions listed in Boot Menu, for example
upgrading the Boot ROM and application. For information about other functions, refer
to Comware V3 Operation Manual.
Caution:
Upgrade software only when necessary and under the guidance of technical staff.
5.2 Maintaining Software of the RPU
5.2.1 Boot Menu
Software maintenance uses the main Boot ROM menu and the small Boot ROM menu,
for downloading and booting the application image and the main Boot ROM system
respectively.
Build up a configuration environment according to the section ”Setting up a
Configuration Environment” in Chapter 4 “Starting and Configuring the Router”. Start
the router; the console screen displays:
Do you want to go on checking sdram? Yes or not(Y/N)
Enter <N>. The screen displays:
