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.

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.
