The HP NC112T PCI Express Gigabit Server Adapter is a high-performance PCI Express, single port,
gigabit server adapter that delivers up to 1000Mbps Ethernet over twisted-pair (copper) category 5 or
better cabling. It is powered by an Intel 82574L chipset. The NC112T adapter, which ships with a
standard-height chassis bracket attached and also includes a low-profile chassis bracket, has a fully
integrated controller capable of auto-negotiating a link at 10, 100, or 1000Mbps. Network connection is
made through an RJ-45 connector. LED indicators show the link, activity, and speed. See LED indicators
(on page 6) for details. The adapter is a supported option for selected HP ProLiant servers. The adapter
must be installed in a PCI Express slot.
The NC112T adapter supports IPv4 and IPv6 offload. For the latest functionality, features, and operating
system support for this adapter, see the HP website
UTP CAT5 cable
The NC112T adapter can use existing UTP CAT5 (or better) cable to deliver Gigabit Ethernet over
copper, according to the IEEE 802.3ab specifications. For new installations, CAT5e (enhanced CAT5)
cable is recommended.
For troubleshooting and other information about cabling, see UTP Cable Specifications (on page 11).
The NC112T adapter has an auto-negotiating 10/100/1000 RJ-45 port. LED indicators show
activity/link and port speed. Standard-height and low-profile brackets are shown below with an RJ-45
port and LED indicators.
