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 that your
network infrastructure is capable of the necessary throughput to match the
server’s I/O capacity.
SVGA with 8 MB video memory (ATI RageXL chipset)
Three USB ports: One on the front panel and two on the rear
All ports are USB 2.0 compliant.
One RS-232 serial port, located on the rear of the machine
Remote Supervisor Adapter with:
– 10/100 Ethernet port management port
– RS-485 ASM interconnect bus
– Serial port
– External power port
There are no PS/2 keyboard or mouse ports on the x455. USB keyboard and
mice are supported. If you require KVM support, the 1.5 M USB Conversion
Option (UCO) (part number 73P5832) enables the x455 to be attached to one of
the Advanced Connectivity Technology (ACT) switches for common management
within the rack. This smart cable is plugged into the USB and video ports on the
server. It converts KVM signals to CAT5 signals for transmission over a CAT5
cable to either a Remote Console Manager (RCM) or Local Console Manager
(LCM). USB servers can be managed on the same set of switches as legacy
PS/2-based or C2T-based KVM servers.
1.5 Remote Supervisor Adapter
The x454 includes a Remote Supervisor Adapter (RSA), which is positioned
horizontally in a dedicated PCI-X slot beneath the PCI-X adapter area of the
system.
