1Router Overview
Introduction
The HP A6616 router (hereinafter referred to as the A6616) is a high-performance service
router developed by Hewlett Packard (hereinafter referred to as HP), serving as the core router
on a carrier network or large enterprise network.
The A6616 adopts two main processing units (MPUs), redundant power modules, and a
distributed modular architecture. Abundant optional modules are available so that the two
service routers can have a powerful processing capability and support flexible configuration to
fully meet the requirements of the carrier network and enterprise network. The A6616 can work
at the core layer of small- and medium-sized MANs or provincial networks.
With the high-performance microprocessor technology, advanced hardware architecture and HP
proprietary Comware V5 platform, the A6616 provides high service processing capacity, flexible
service scalability, and high reliability. The A6616 can work together with other HP network
routers to provide comprehensive network solutions for medium- and large-sized enterprises,
carriers, and users in the fields of electric power, finance, taxation, public security, railway and
education. The full compliance with national and international standards ensures interoperability
with products of other manufacturers at different layers.
The A6616 supports high-speed interface modules (HIMs) and provide a bus processing
capability up to 10 Gbps, which can meet the high-speed performance requirements of users. In
addition, the A6616 is compatible with some multi-functional interface modules (MIMs) of the HP
MSR/AR series routers to guarantee the smooth upgrade from narrowband access to
broadband access, improve the competitiveness, and protect existing investments.
You can configure MPUs and flexible interface platforms (FIPs) on the A6616 as needed. Table
1-1 describes MPUs' support for FIPs on the A6616.

RSE-X1 Not supported Supported Not supported Supported
The A6616 supports two types of MPUs, route processing engine (RPE) and route switch
engine (RSE).
To facilitate description, the term "FIP" is used throughout this document to refer to the FIP-
100, FIP-110, FIP-200, and FIP-210 if not otherwise specified.
The FIP-100 and FIP-110 support MIMs only.
The FIP-200 and FIP-210 support MIMs, HIMs, and HIM/MIM intermixing.
For details about the slot arrangement, refer to Chapter 2 "Arranging Slots and Numbering
Interfaces."
For details about installation and removal of HIMs and MIMs, refer to Chapter 4 "Installing the
Router.”

Status Meaning
Solid green The power module is working normally.
Solid red The power module is faulty.
Intelligent Power Supply Management
The A6616 supports either AC or DC power supply. Power modules of different types cannot
operate on the same A6616.
The A6616 provides four power module slots. You are recommended to configure power
redundancy backup to ensure high reliability.
The A6616 supports FIP power-on priorities management, power redundancy management,
and power management. These functions effectively prevent service anomalies caused by
power failure.
The A6616 supports online insertion but not online removal of a power module.
Online refers to first switching off the power module and then removing it from the router or
inserting it into the router. Before doing that, make sure that the router is configured with
redundant power modules and the system services are running normally.
FIP power-on priorities management
The A6616 provides eight FIP slots, including Slot 0 through Slot 3, and Slot 6 through Slot 9.
You can configure FIPs with different power-on priorities, namely, Level 1 through Level 3.
Level 1 is the highest power-on priority, while Level 3 is the lowest.
The default power-on priority of an inserted FIP is Level 2. Use the power-supply policy
priority priority level slot slot number command to set the power-on priority of an inserted FIP.
Power redundancy management
To avoid service interruption caused by power module failure during the operation of a device,
you are recommended to configure power redundancy for the device. The redundant power
modules can automatically implement backup without further configurations.
Use the display power-supply command to view the system power information, so that you
can take countermeasures in time.

Take 650 W power modules for example. If a device requires an actual operation power of 1000
W, you need to install two 650 W power modules to ensure normal working of the device.
Optionally, you can install altogether three such power modules with one of them for power
redundancy or four such power modules with two of them for power redundancy.
Power management
The A6616 supports power management. This function prevents a single faulty power module
from affecting the whole router, and hence ensures the normal operation of services.
To be more specific, after the MPU starts up, the online FIPs are powered on in descending
order of their priorities. FIPs with the same priority are powered on in ascending order of their
slot numbers. This process goes on until the system power is insufficient or all the FIPs are
powered on.
For example, on an A6616, suppose that the system power is sufficient. If FIP-200s are inserted
into Slot 1, Slot 3, Slot 7, and Slot 9 with power-on priorities Level 2, Level 3, Level 2, and Level
1 respectively, the FIP-200s are powered on in the order of Slot 9, Slot 1, Slot 7, and Slot 3.
Use the display power-supply command or the display power-supply verbose command to
view the power management information. You can manually power on or power off the FIPs as
needed, in order to adjust the available system power. Use the undo remove slot slot-number
command to power on the FIP in the specified slot. Use the remove slot slot-number command
to power off the FIP forcibly.
Do not power off a running power module. Otherwise, the power supply may be insufficient, and
a system power failure or FIP power failure may occur.
For details about commands in intelligent power supply management, refer to Device
Management in the System Volume of HP SR6600 Routers User Manual.

System Software
The router uses the Comware V5 software platform, HP's core software platform.
Based on the IPv4/IPv6 dual stack, the Comware V5 software platform integrates link-layer
protocols, routing, Multi-Protocol Label Switching (MPLS), Virtual Private Network (VPN), quality
of service (QoS), security, and multicast technologies. It is scalable and portable because it
adopts a modular architecture and effectively encapsulates and masks different operating
systems and hardware. The Comware V5 software platform is the basis of all series of IP
network products of HP.

Memory
A memory module is used for storing the data exchanged between the system and the CPU.
The default memory size of the RPE-X1 is 1 GB (one 1 GB memory module) and the maximum
memory size is 2 GB. An RPE-X1 provides two memory slots in which you can insert two DDR2
SDRAMs of different sizes.
The DDR2 SDRAMs for the RPE-X1 have two sizes:
DDR2 SDRAM-512MB
DDR2 SDRAM-1GB
The default memory size of the RSE-X1 is 2 GB (two 1 GB memory modules) and the maximum
memory size is 2 GB. An RSE-X1 provides two memory slots in which you can insert two DDR2
SDRAM-1GB modules.
NVRAM

dialup backup. You need to connect the local modem to the remote modem through PSTN and
then to the remote device for remote system deb
ugging, configuration, maintenance, and
management. In the event that the console port fails, the AUX port can be connected to a
terminal as a backup port of the console port. For details, refer to “Using the Port AUX as
Backup Console Port” in Chapter 7 “
Troubleshooting.”

USB interfaces
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 device fully supports USB 1.1. The USB interfaces of the device allow for conven
