Planning Your Upgrade |
This chapter provides important information, including requirements, configurations, and limitations for upgrading your systems. Before you upgrade your systems, read this chapter.
This chapter contains the following topics:
The Netra CP2500 board is the next-generation processor board for use in Netra CT 410/810 servers.
The Netra CP2500 board and the corresponding rear transition modules (RTMs) are compatible (will not cause damage) with installations of the Netra CP2140 board or Netra CP2160 board. Some features and functions of the Netra CP2500, however, are not available or usable in these installations. In addition to the board and RTM, other hardware upgrades are required to use the Netra CP2500 board.
The Netra CP2500 board is not designed to be a one-to-one feature-compatible hardware replacement for the host Netra CP2140 cPCI board or satellite Netra CP2160 cPCI board. Before replacing a host Netra CP2140 cPCI board or satellite Netra CP2160 cPCI board, compare the features to ensure that the Netra CP2500 board provides the features you want for your system.
The Netra CP2500 board software is fully feature-compatible with other boards when installed in a Netra 810 server or Netra 410 server chassis. All applications you currently run can be run in a server upgraded with the Netra CP2500 board. Software and firmware upgrades are necessary. For information about the software and firmware upgrades that are necessary, refer to Netra CT410/810 Server Release Notes (819-2739).
This section describes the minimum power-supply availability, firmware, software, and hardware requirements necessary to install a Netra CP2500 board in a system that has no other Netra CP2500 boards installed.
After upgrading the firmware and software, you can replace a host or satellite board with a Netra CP2500 board.
Regardless of whether your system replaces a Netra CP2140 board or Netra CP2160 board with a Netra CP2500 board, the same Solaris OS version is required.
The following software upgrades are necessary:
Optionally, you might want to include the Acceptable_Fru_Types configuration from the alarm card command line interface (CLI).
For instructions on upgrading the software and firmware, refer to Netra CT410/810 Server Release Notes (819-2739).
Note - Upgrade the hardware before upgrading the software and firmware. |
Different boards can be mixed within a Netra CT 410/810 system. However, a board might fail to function if the following rules are not followed:
|
Caution - The maximum number of Netra CP2500 boards that you can install on a any Netra CT 410/810 system is three. Do not exceed this maximum. |
The number of boards you can install could be fewer than three if your systems are customized or configured with third-party components. To support the maximum number of boards, your system must have enough power supply. To calculate power-supply requirements, see Power Supply Requirements.
The following hardware components are required and included in the host upgrade kits, based on your server chassis:
The following hardware components are required to install a satellite board:
After you upgrade your systems with a Netra CP2500 board and required components, you might want to add boards immediately or later to increase performance. After you have upgraded the required hardware components, you can add boards up to the maximum allowed. The following are the requirements for adding each board.
Note - Netra CP2500 host boards and rear transition modules for host boards (RTM-H) are not provided as optional components because they are available in the host upgrade kits. |
For standard and supported configurations of the Netra 410/810 servers, the power supply is sufficient to accommodate up to three Netra CP2500 boards.
If your systems are customized or configured with third-party components, the number of boards you can install could be fewer than three, based upon the power supply. In this case, calculate your system's power requirements to verify you have sufficient power for the number of boards you want to install in your system. Contact your original equipment manufacturer's (OEM) customer support for information about their components.
To Calculate the Power Supply Requirements |
1. Compute the total cPCI power requirements of your planned configuration.
TABLE 1-1 shows the power requirements of Sun components; use the manufacturer's peak power data for any third-party components. Make sure that you include all add-in components, such as memory configurations, PCI mezzanine card (PMC) add-on boards, and RTMs.
2. Compare your configuration's power requirements with the power available in TABLE 1-2 (Netra 810 server) or TABLE 1-3 (Netra 410 server).
Refer to the Netra CP2500 Board Installation and Technical Reference Manual for additional information about power requirements.
The following table shows the power required for Sun-supplied cPCI components.
Installed cPCI boards must not exceed the power available to the slots. TABLE 1-2 and TABLE 1-3 show power availability for cPCI boards in Netra CT 810 servers and Netra CT410 servers.

This section describes supported configurations. Use the information in this section to determine which allowable configuration matches your system and upgrade needs.
Note - You can install up to three Netra CP2500 boards. This maximum is set due to power-supply limitations. For more information, see Power Supply Requirements. |
The following sections describe the roles of the Netra CP2500 board when used as a host or a satellite CPU.
When a Netra CP2500 board is in the host slot in a Netra CT 410 or Netra CT 810, it acts as the system host CPU. In this role, it is a performance upgrade for the Netra CP2140 host board. All applications that run on the Netra CP2140 board run on a Netra CP2500 host board.
As a host, the Netra CP2500 board manages local resources including the field-replacable units (FRUs) connected to the host's own SCSI interfaces. With the alarm card, the host board acts as the hot-swap controller and manages the dynamic reconfiguration of the following FRUs on the cPCI bus:
When a Netra CP2500 board is in a non-host slot, it acts as a satellite. In this role, it is a performance upgrade for the Netra CP2160 satellite board. The Netra CP2500 board can be managed by either a host Netra CP2140 or a host Netra CP2500 board. All applications that run on the Netra CP2160 run on a Netra CP2500.
The Netra CT 810 server rear access is supported. You can install a maximum of three Netra CP2500 boards. TABLE 1-4 lists the supported configurations.
For new Netra CT 810 servers ordered from Sun, one Netra CP2500 board is preinstalled in the host slot.
|
Caution - In the Netra CT 810, the Netra CP2500 board is not supported in slot 6 or slot 7. This configuration results in higher operating temperatures that trigger equipment shut down. |
The Netra CT 410 server rear access (diskfull) is supported. You can install up to three Netra CP2500 boards. TABLE 1-5 lists the supported configurations.
For new Netra CT 410 servers ordered from Sun, one Netra CP2500 board is preinstalled in the host slot.
