Netra CP2500 Board Overview

The Netra CP2500 board is a crucial building block that network equipment providers (NEPs) and carriers can use when scaling and improving the availability of carrier-grade systems. Based on industry standards, the Netra CP2500 board provides high performance and is powered by a UltraSPARC® IIIi processor. The board enables you to add a third-party PCI mezzanine card (PMC) to tailor solutions to your specific application needs.

When replacing the Netra CP2140 host and Netra CP2160 satellite CompactPCI (cPCI) boards in the Netra CT 410 and 810 servers, the Netra CP2500 board provides a sizeable increase in Netra CT server performance.

The Netra CP2500 board provides PCI Industrial Computers Manufacturers' Group (PICMG) CompactPCI Packet Switched Backplane (cPSB) compliance. To meet the requirements of the communications and service provider environments, the board is NEBS Level 3 compliant, and the Netra CT 410 and 810 servers remain NEBS Level 3 certified with the Netra CP2500 board installed.

This chapter contains the following sections:

The Netra CP2500 board can also be mounted in various cPSB enclosures, such as those shown in FIGURE 1-3 and FIGURE 1-4.

You can deploy the Netra CP2500 boards in a number of cPSB configurations to suit your specific requirements. For example, the board can be configured to boot from a network as a diskless client over either a cPSB backplane network or an RTM Ethernet network connection. Alternatively, the Netra CP2500 board can be purchased with an installed PMC hard drive, which can provide local disk support I/O and may optionally be used as a boot path. The installation procedure is independent of the type of enclosure, whether a floor-mounting rack or a bench-top cabinet is used.

1.2.1 PMC Modules

While the Netra CP2500 board has only one serial port on the front panel, IHV-built PMC modules can provide additional I/O to the front panel. PMC modules decode their custom I/O from the Netra board's on-board PCI bus signals.



Note - Sun does not support installing a PMC interface module (PIM) device on either the RTM-S or the RTM-H.





Note - The Netra CP2500 board has one PMC I/O slot. If you purchase a board with a PMC disk drive, you will not be able to install an additional PMC device.



1.2.2 Rear Transition Modules

There are two optional transition modules (RTMs) available for the Netra CP2500 board:

You can install the RTM-H and RTM-S into rear slots of the Netra CT server, opposite the appropriate Netra CP2500 board. These rear transition modules connect with the board's CompactPCI connectors through the Netra CT server midplane pins and carry four Ethernet ports, and two serial ports out to its rear panel. Refer to the Netra CT Server Installation Guide (819-2740) for installation and cabling instructions.

After setting a DIP switch on the Netra CP2500 board and two banks of DIP switches on the RTM-S, you can install the Netra CP2500 board and the RTM-S into a cPSB chassis (see FIGURE 1-7). See Chapter 2 for cPSB chassis installation instructions, including how to set these mechanical switches.



Note - For complete information about the two Netra CP2500 rear transition modules, refer to the Netra CP2500 Rear Transition Module Installation and Technical Reference Manual (819-1753).

FIGURE 1-7 Netra CP2500 Board and a RTM-S in a Typical cPSB Chassis

Figure showing the installation of a board and an RTM-S in corresponding cPSB slots.




Note - To satisfy EMI compliance standards, you must use shielded cables for serial ports when using an RTM with the Netra CP2500 board. The shields for all shielded cables must be terminated on both ends. You can use unshielded cables on Ethernet ports.



The customer can order a Netra CP2500 RTM-S, build a custom card, or buy from an independent hardware vendor (IHV). A minimal set of I/O must provide for a boot path for the host board, and for a path for console I/O to deliver commands and to read board and system status.

TABLE 1-3 describes the possible Netra CP2500 board boot and I/O configurations. Sun Microsystems provide the Netra CP2500 boards and compatible RTMs. These RTMs provide four Ethernet RJ45 ports from the host to the rear of the system. These ports can optionally be used to accomplish a network boot as a diskless client. The other configurations require IHV hardware.

  • Switches set to non-cPSB-mode - Ethernet I/O routed to the four RJ-45 ports on the RTM-S.

Optional third-party SCSI or IDE PMC interface card

A third-party PMC interface card can be installed to provide external SCSI, serial, or IDE I/O.



1.3 Hot-Swap Support

This section briefly discusses the hot-swap support on the Netra CP2500 board.

Refer to the PICMG CompactPCI Hot-Swap Specification, for a detailed description of this subject. In general, the hot-swap process includes the orderly connection of the hardware and software.

This process uses hardware connection control to connect the hardware in an orderly sequence. Hot-swapping uses backplane pins of different lengths to perform signal sequencing, which protects the hardware and avoids corrupting the backplane bus.

There are three models of hot-swap described in the PICMG CompactPCI Hot-Swap Specification - basic hot-swap, full hot-swap, and high-availability (HA) hot-swap.

TABLE 1-4 lists the hot-swap support details when a Netra CP2500 board is installed in a Netra CT 410 or 810 server, or when the board functions as a cPSB node board in a cPSB enclosure.
