hot-pluggable. You must use software commands to turn off the modem before you
remove it.
USB Ports
Four external USB 2.0 ports, three on the back of the system and one on the front
panel, are user-configurable and support the keyboard and mouse.
PCI Adapter Slots
There are four user-configurable slots per CPU-I/O enclosure. PCI adapter slots 1 and
2 support only low-profile PCI adapters. PCI adapter slots 3 and 4, on the optional PCIe
or PCI-X riser available for ftServer 4500 and 6300 systems, support full-height and
low-profile PCI adapters.
The PCI slots support low-profile or full-height adapters of the following dimensions:
• Slots 1 and 2 (on motherboard)—low-profile PCIe adapters only; maximum
dimensions: 6.6 in. (167.75 mm) long, 2.536 in (64.41 mm) high
• Slot 3 (upper slot on PCIe riser or PCI-X riser)—low-profile or full-height adapters;
maximum dimensions: 7.7 in (195.84 mm) long, 4.2 in (106.68 mm) high
• Slot 4 (lower slot on PCIe riser or PCI-X riser)—low-profile or full-height adapters;
maximum dimensions: 6.6 in (167.64 mm) long, 4.2 in (106.68 mm) high
The low-profile PCI slots are physically labeled 1 and 2. The full-height slots are
labeled 3 (the upper slot) and 4 (lower). The numbers are silk-screened on the
enclosure exterior and are the same numbers that identify the slots in the software.
See the
Stratus ftServer Systems: PCI Adapter Guide
(R461) for detailed information
about PCI adapters.
PCI Riser
An optional right-angle expansion PCI riser accommodates full-height PCI adapters in
the low-profile interior of the 2U (a
U
is a rack unit: 1.75 in.) CPU-I/O enclosure. PCI
risers hold the connected adapters in a position parallel to the motherboard.
ftServer 4500 and 6300 systems support two models of PCI riser: PCIe and PCI-X.
Ethernet Ports
Each CPU-I/O enclosure contains two Ethernet ports that operate at 10, 100, or 1000
megabits per second (Mbps) and connect to the embedded Ethernet controller.
