Main processing units

A main processing unit (MPU) calculates routes, manages the FIB, supervises and controls the system,

and provides a precise system clock and the real time clock (RTC) function.

The MPUs available for the SR6604 and SR6608 routers include half-slot wide RPE-X1 and one-slot wide

RSE-X1. If you order an RPE-X1 MPU, you must also order an RPE-X1 carrier. For the MPU specifications,

see “Appendix A Technical specifications.

”

For how to install an MPU, see “Installing the router.”

Flexible interface platform modules

A flexible interface platform module is a processing engine and you can install different interface

modules on a FIP to support different network services as needed. This section describes the flexible

interface platform (FIP) modules available for the H3C SR6604 and SR6608 routers.

When you order or install a FIP, see” Appendix B Hardware compatibility matrices” to check the FIP and

MPU compatibility.

FIP-100

You can plug up to four MIMs into the FIP-100 to provide high-density narrowband aggregation and

protect the investment in the MIMs for MSR routers.

Service aggregation platform modules

A service aggregation platform (SAP) module provides network ports for receiving packets from the

network and sending packets to the network. This section describes the SAPs available for the H3C

SR6604 and SR6608 routers.

SAP-48GBE

The SAP-48GBE has 48 high-performance RJ-45 ports that can be both routed and switched. One

two-color LED is available for each port to indicate their activity and link status. The module also has a

RUN LED to indicate the module operating status.

SAP-24GBP

The SAP-24GBP has 24 high-performance fiber SFP ports that can be both routed and switched. One

two-color LED is available for each port to indicate their activity and link status. The module also has a

RUN LED to indicate the module operating status.

OAP cards

You can install an OAP card in a service module slot to provide value-added services such as security

and voice. An OAP card is OAA-enabled and has an independent operating system. You can follow the

OAA standard to customize your own OAP cards.

For the OAP cards available for the routers and their compatibility, see “Appendix B Hardware

co

mpatibility matrixes.” For more information about the OAP cards, see the H3C SR6600 Routers

Interface Module Guide.

HIMs and MIMs

You can install HIMs to provide 10-Gbps service processing capability and install MIMs to provide

high-density narrowband aggregation. The HIMs and MIMs can offer a variety of interfaces, including

serial, Ethernet, POS, and E1.

The H3C SR6604 and SR6608 routers support the mix of HIMs and MIMs.

For the HIMs and MIMs available for the routers and their compatibility, see “Appendix B Hardware

co

mpatibility matrixes.”

Power supplies

The H3C SR6604 and SR6608 routers can be DC-powered or AC-powered. You can install two power

supplies in your router, and they must be the same model.

The H3C SR6604 and SR6608 routers use hot swappable power supplies. You can install one power

supply, or for redundancy, two power supplies for your routers.

AC-input power supply

The AC input voltage range is 100 VAC to 240 VAC at 50 Hz to 60 Hz.
