Netra CP2300 cPSB Board Description

Note - This chapter gives general information on the Netra CP2300 cPSB board. For more detailed information, refer to the Netra CP2300 cPSB board documentation.

The Netra CP2300 cPSB 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 CP2300 board provides high performance and is powered by a 650-MHz UltraSPARC® IIi processor.

The Netra CP2300 board enables customers to mix and match third-party PCI mezzanine cards (PMCs), making it easier for them to tailor solutions to their specific application needs. The Netra CP2300 board provides PCI Industrial Computers Manufacturers' Group (PICMG) CompactPCI packet-switched backplane compliance (for details, see TABLE 5-1) and is NEBS Level 3-certified to meet the requirements of the communications and service provider environments.

Netra CP2300 cPSB Board Features

The Netra CP2300 board is a cPSB single-board computer designed for high-performance embedded, compute density applications. The Netra CP2300 board has system management controller (SMC) capability that supports hot-swap operations, system management, and environmental monitoring. Powered by a 650-MHz UltraSPARC IIi processor, with full utilization of the PMC slots, the Netra CP2300 board is an ideal platform for NEPs to use for a wide variety of Solaris applications.

FIGURE 5-1 displays an illustration of a typical Netra CP2300 board, and TABLE 5-1 lists a summary of features of the board.

Note - For EMI compliance of front access ports, use shielded cables on all I/O ports. The shields for all shielded cables must be terminated on both ends.

Netra CP2300 System Configurations

The boards can be deployed in various electrical configurations to suit each end-user requirement. For example, a board can be configured to boot from a network as a diskless client with either a cPSB or rear transition card network connection. Alternatively, industry-standard PMC and PIM hardware from IHVs can be installed to provide local disk I/O, which can 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. The Netra CP2300 board has fixed on-board memory and connectors for additional memory.

PMC and PIM Modules

The Netra CP2300 board has one serial port on the front panel. The IHV-built PMC modules provide additional I/O to the front panels. PMC modules decode their custom I/O from the Netra board's on-board PCI bus A signals.

Rear Transition Card

The optional Netra CP2300 cPSB transition card (Sun part number, XCP2300-TRN) installs into the rear of the Netra CT 820 server, opposite the Netra CP2300 board. The transition card connects with the host CompactPCI connectors through the backplane pins and carries two serial ports and a USB port out to its rear-panel flange. The transition card contains a 40-pin EIDE connector that is switch selectable and mutually exclusive with the PIM A connector I/O pins 1-29. The transition card also provides two switch-selectable RJ-45 10/100 Ethernet connectors, which are mutually exclusive with cPSB network interfaces. The Netra CP2300 board SW3 DIP switch controls the access to these Ethernet ports. Refer to the Netra CT 820 Server Service Manual for more information on setting the Ethernet networking for the Netra CP2300 board.

Note - When the transition card is used with the Netra CP2300 board, shielded cables are required for serial and USB I/O ports, and unshielded cables can be used on Ethernet ports in order to satisfy EMI compliance standards. The shields for all shielded cables must be terminated on both ends.

The transition card can also be fitted with IHV PCI Interface Modules (PIMs) that are configured to bring I/O channels to the unit rear panel. A PIM hardware kit includes a card for the PMC slot and a card for the PIM slot on the transition card. A PIM is a rear-panel extension added to a PMC module. When the PIM I/O is configured, the front PMC I/O output is not accessible.

The customer can order the Netra CP2300 transition card, build a custom card, or buy a transition card from an 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.

Possible boot and console configurations are described in TABLE 5-2. Sun Microsystems provides the Netra CP2300 board and a compatible Netra CP2300 transition card. This transition card provides two 10/100 Ethernet RJ45 ports from the host to the rear of the system, which can optionally be used to accomplish a network boot as a diskless client. The other configurations require IHV hardware.
