Overview of the Netra CP2300 cPSB Board
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 1-1) and is NEBS Level 3 certified to meet the requirements of the communications and service provider environments.
This chapter contains the following sections:
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, and including two the PMC slots, the Netra CP2300 board is an ideal platform for NEPs to use for a wide variety of Solaris applications.
FIGURE 1-1 displays an illustration of a typical Netra CP2300 board, and TABLE 1-1 lists a summary of features of the board.
Estimated at 22W (typical) and 26W (peak maximum) at 650 MHz, and
The Netra CP2300 boards can be mounted in various enclosures, such as shown in FIGURE 1-2. The boards can be deployed in various electrical configurations to suit each end-user requirement. For example, the 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 independent hardware vendors (IHVs) can be installed to provide local disk I/O, which 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. The Netra CP2300 board has fixed on-board memory and connectors for additional memory.
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. A transition card can also be fitted with IHV PCI Interface Modules (PIM) to bring I/O channels to the rear of the unit. See Section 5.4.2, PMC and PIM Interface for further information.
The optional Netra CP2300 cPSB transition card (Sun part number, XCP2300-TRN) installs into the rear of the cPSB enclosure, opposite the Netra CP2300 board (see FIGURE 1-4). 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 (see Section B.5, DIP Switch Settings for more information).
FIGURE 1-4 show the physical relationship between the board, transition card, and the backplane in a typical cPSB system.
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 PIM modules which 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 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.
Possible boot and console configurations are described in TABLE 1-2. 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.
When optional transition card is installed, the card's Serial port A will become the path of the default console I/O (see FIGURE 1-3 for location).
This section briefly discusses the hot-swap support on the Netra CP2300 board.
See Appendix D for a reference to the PICMG CompactPCI Hot Swap Specification which provides 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. This process includes the use of backplane pins of different lengths to accomplish signal sequencing to protect the hardware and avoid 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 1-3 lists the hot-swap support details when a Netra CP2300 board functions as a node board.
Sun provides these items to customer order:
The transition card enables rear system I/O access to the network, to a boot device, and to a console terminal (shown in FIGURE 1-3).
This transition card is optional and must be ordered separately from the Netra CP2300 board. See the Netra CP2300 cPSB Transition Card Installation and Technical Reference Manual (816-7188-xx) for complete details about the transition card.
You must acquire the following components if needed:
See Section B.3, Front Panel Serial Connector and Netra CP2300 cPSB Transition Card Installation and Technical Reference Manual (816-7188-xx) for descriptions of I/O connections.
The Solaris 8 2/02 operating environment, or subsequent compatible versions, may be used with the Netra CP2300 cPSB board. Refer to the Netra CP2300 cPSB Board Release Notes (817-1741-xx) for more Solaris operating environment information, including a list of the required software patches.
