Note
If a standard (non-USB) keyboard is attached to
the keyboard port, the USB ports are disabled
while the power-on self-test (POST) is running
and no USB devices will work during POST.
Ethernet Connector: The server has one RJ-45
Ethernet connector. This connector is for attachment
of the network to the integrated 10BASE-T or
100BASE-TX, twisted-pair transceiver.
Expansion Slots: The server has one industry
standard architecture (ISA) expansion slot and six
peripheral component interconnect (PCI) expansion
slots. Four of the PCI slots support hot-plug PCI
adapters.
You can install PCI or ISA adapters. Many adapters
provide bus-master capabilities, which enable the
adapters to perform operations without interrupting
the system microprocessors.
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 is on. The
meaning of the Attention lights is defined by the
operating system. Refer to the operating system
documentation to determine if it supports hot-plug PCI
adapters and, if so, what the Attention lights indicate.
Power Connector: The power cord for power supply
1 connects here. (The power connector for the
additional optional power supply is covered by the
filler panel.)
External Connector Knockout: The server has
three external connector knockouts that can be used
when you install options, such as the external SCSI
cable option.
Note
For pin assignments and other details about these
connectors, see “External options” on page 165.
