2 Netra t 1400/1405 Installation and User’s Guide • September 1999
The system unit has the following features:
■ Rack mounting enclosure with n + 1 redundant hot swap –48VDC / –60VDC
(Netra t 1400) or AC (Netra t 1405) power supplies
■ support for up to four modular 440MHz UltraSPARC II processors with
4Mbyte cache
■ UltraSPARC Port Architecture (UPA) coherent memory interconnect
■ use of DIMMs, with an interleaved memory system. Each pair of DIMM slots
(four rows of two pairs each) accepts 64 or 256 tMbyte DIMM modules.
Populating with two pairs of identical capacity DIMMs enables the memory
controller to interleave and overlap, providing optimal system performance.
There are a total of 16 DIMM slots supplying a minimum of 256Mbyte
(4 x 64Mbyte) and a maximum of 4Gbyte (16 x 256Mbyte) of memory.
■ Four PCI slots:
■ two 33MHz, 64- or 32-bit, 5VDC slots
■ one 33MHz 32-bit only 5VDC slot
■ one 66MHz or 33MHz, 64- or 32-bit, 3.3VDC slot
Universal PCI cards can be used in any of the four PCI slots.
■ 10/100 Megabit per second (Mbps) Ethernet
■ 40Mb/s Fast-20 (UltraSCSI) disk subsystem supporting up to four 18Gbyte disk
drives
■ Two RS232/423 DB-25 serial ports (asynchronous protocols)
■ Parallel port
■ External Fast-20 (UltraSCSI) 68-pin port
■ Up to two SCSI removable media drives (CD-ROM or DAT or both)
■ Alarms card implementing Lights Out Management
