Input/output connectors and expansion
slots
The following illustration shows the expansion slots and
the input/output connectors (ports) on the rear of the
server.
.1/
PCI Expansion Slots: The server has five
peripheral component interconnect (PCI) expansion
slots. Four of the PCI slots support hot-plug PCI
adapters. The remaining, non-hot-plug PCI slot
supports only a short adapter.
Many adapters provide bus-master capabilities,
which enable the adapters to perform operations
without interrupting the system microprocessors.
.2/
ISA Expansion Slot: The server has one industry
standard architecture (ISA) expansion slot.
Many adapters provide bus-master capabilities,
which enable the adapters to perform operations
without interrupting the system microprocessors.
.3/
Parallel Connector: A signal cable for a parallel
device, such as a printer, connects here.
.4/
Serial A Connector: A serial signal cable for a
modem or other serial device connects to this 9-pin
serial connector. Serial port A can be shared by
the Netfinity Advanced System Management
Processor and the operating system. See “Devices
and I/O ports” on page 24 for port assignment
information. If you are using a 25-pin signal cable,
you need a 9-pin-to-25-pin adapter cable.
.5/
Attention Lights for Hot-Plug PCI Slots: Each
hot-plug PCI slot has an Attention light that is
visible from the rear of the server. An Attention
light flashes approximately once per second when it
