1-2 Compaq NC3134 Fast Ethernet Server Adapter User Guide
Hardware Overview
IMPORTANT: Two other devices, described separately in the Compaq NC3131 Fast Ethernet Server
Adapter User Guide (available on the Compaq Website at www.compaq.com/support), are compatible
with the NC3134 and the upgrade modules and drivers listed in this guide. These devices are:
■ The NC3131 Fast Ethernet Server Adapter, which supports all the upgrade modules described in this
guide
■ The NC3132 Dual 10/100 Upgrade Module, which you can install in the NC3131 or the NC3134 Fast
Ethernet Server Adapters
The Compaq NC3134 Fast Ethernet server adapter is a high performance, upgradeable adapter
with two fully-integrated 10BASE-T/100BASE-TX networking chips. The adapter contains a
sophisticated 32-bit MAC with enhanced scatter-gather and bus-mastering capabilities. Its true
32-bit architecture enables it to perform high-speed data transfers on the PCI bus using four
DMA channels. It can process high-level commands and perform multiple operations without
processor intervention.
The NC3134 adapter operates in a standard 32-bit PCI slot, supports both 32-bit and 64-bit
systems, and can operate at 33MHz or 66MHz depending on the system.
NC3134 Adapter
The NC3134 adapter has two RJ-45 dual-speed ports. LEDs on each port indicate link, activity,
and port speed.
NOTE: Transmission speed is indicated by the color of the LNK and ACT LED indicators. See Table 1-2
for more information.
