Figure 2-5: The rear view of the Netra 240 server shows a wide range of networking and I/O options.
Serial Ports
Serial ports provide a convenient way to connect Netra 240 servers to terminal and other serial devices using two asynchronous serial ports. The serial A port (RJ-45 connector) is used as a console and serial interface to the System Management Controller ASIC and ALOM. The serial B port (DB-9 connector) can be used for general serial connectivity and supports asynchronous transfers at up to 460 Kbaud.
USB Ports
Two USB ports provide convenient connectivity to a keyboard and mouse as well as hand-held devices for configu- ration management. In addition, third-party, USB-based peripheral devices, such as ZIP drives, printers, and external CD-ROM and DVD-ROM drives can be attached using the USB ports.
UltraSCSI Port
An external Ultra160 SCSI connector is available for attaching additional UltraSCSI devices such as Sun StorEdge™ disk arrays.
PCI Card Slots
The Netra 240 server provides one full-length, 64-bit, 33/66-MHz PCI slot and two half-length, 64-bit, 33-MHz PCI slots—enabling a total of three PCI cards to be added to the system. These additional PCI cards allow special- purpose functionality supported by Sun or Telecom-industry vendors such as external connectivity to other types of networks, including ATM, Sonet, Fibre channel, T3, and others.
Power Supplies
Power connection to the Netra 240 server is also located on the back panel. The Netra 240 server features hot- swappable, dual-redundant power supply units, each with separate power connections for enhanced reliability and availability. In the absence of one power supply unit, the other unit can adequately supply required power to the Netra 240 server.
Sun Crypto Accelerator 500 Board
The Netra 240 server supports the Sun Crypto Accelerator 500 (SCA 500) daughter card, an optional hardware cryptographic accelerator module that installs in the system without occupying an additional PCI slot. Ideal for e-commerce or other applications that benefit from SSL (Secure Socket Layer) acceleration, the SCA 500 board, with no external interfaces, functions as a cryptographic co-processor to accelerate public key and symmetric cryptography.
