Note: The ability to hot-replace a failed DIMM or hot-add additional DIMMs are currently not supported. 1.8 PCI subsystem As shown in Figure 1-4 on page 8, there are six PCI-X slots internal to the x440: Two 133 MHz slots, which accept 32 or 64-bit, 3.3 V, PCI or PCI-X adapters, from 33-133 MHz Two 100 MHz slots, which accept 32 or 64-bit, 3.3 V, PCI or PCI-X adapters, from 33-100 MHz Two 66 MHz slots, which accept 32 or 64-bit, 3.3 V, 33 or 66 MHz, PCI or PCI-X adapters See 3.1.3, "PCI slot configuration" on page 68 for details on what adapters are supported and in what combinations. The PCI subsystem also supplies these I/O devices: Two Wide Ultra 160 SCSI ports, one internal and one external (Adaptec AIC-7899 chipset) Gigabit Ethernet port (Broadcom 5700 chipset) The x440 was the first xSeries server to offer a Gigabit Ethernet controller integrated standard in the system. The x440 includes a single-port Broadcom BCM5700 10/100/1000 Base-T MAC (Media Access Controller) on a PCI 64-bit 66 MHz bus. The BCM5700 supports full and half-duplex performance at all speeds (10/100/1000 Mbps, auto-negotiated) and includes integrated on-chip memory for buffering data transmissions to ensure the highest network performance and dual onboard RISC processors for advanced packet parsing and backwards compatibility with today's 10/100 network. The Broadcom controller also includes software support for failover, layer-3 load balancing, and comprehensive diagnostics. Category 5 or better Ethernet cabling is required with RJ-45 connectors. If you plan to implement a Gigabit Ethernet connection, ensure your network infrastructure is capable of the necessary throughput to match the server's I/O capacity. SVGA with 8 MB video memory (S3 Savage4 Pro chipset) Three USB ports (one on front panel, two on rear) Remote Supervisor Adapter (RS-485 ASM interconnect bus, 10/100 Ethernet and serial ports) Chapter 1.
