Chapter 1. Technical description 23
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)
