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: Your 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: Your 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 your operating system. Refer to your 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: Your 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. Netfinity 5500 - Type 8660 195
