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.

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 refer to the table above when distinguishing between or preparing these two types of
Ethernet cables.
When preparing Ethernet cables, please follow the chromatogram given in the table to arrange
the wires. Otherwise communication quality will be affected even if the devices at both ends are
connected.
When preparing Ethernet cables, use shielded cables preferentially for electromagnetic
compatibility (EMC).
6) Fiber connecting a 1000 Mbps optical Ethernet interface
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 hot-
swappable.
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
(1) USB interface 0 (2) USB interface 1 (3) USB interface 1 LED
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.
RESET Button
To reset the router, you can press the RESET button.
The SYS LED goes off when the router is reset, flashes fast (at 8 Hz) when it is booting, and
flashes slowly (at 1 Hz) when it operates normally.
If you perform no save operation before resetting the router, the current system configuration
will not be saved after the router is reset.
Never press the RESET button when the router is booting (when the SYS LED is blinking fast).
Otherwise, the file system of the router may be damaged.
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.
