What type of network adapter is the HP 138603-B21?

The HP 138603-B21 is an HP NC3134 Fast Ethernet NIC categorized as an Ethernet adapter. It is specifically described as a 2-port 10/100BT Fast Ethernet PCI adapter. This means it provides Fast Ethernet connectivity over twisted pair cabling and is designed to be installed in systems that support PCI expansion slots.

How many network ports does the HP NC3134 provide?

The HP NC3134 Fast Ethernet NIC, identified by SKU 138603-B21, provides two network ports. It is listed as a 2-port 10/100BT Fast Ethernet PCI adapter, allowing a single adapter to support two Fast Ethernet connections. This dual-port configuration can be useful for redundant links or connecting to separate networks.

What network speeds are supported by the HP NC3134 Fast Ethernet NIC?

The HP NC3134, SKU 138603-B21, is a Fast Ethernet NIC described as a 10/100BT adapter. This indicates support for standard Fast Ethernet speeds of 10 megabit per second and 100 megabit per second. It is intended for environments where 10/100BT Fast Ethernet connectivity is sufficient and Gigabit speeds are not required.

Which system interface does the HP 138603-B21 network adapter use?

The HP 138603-B21, corresponding to the NC3134 Fast Ethernet NIC, is described as a PCI adapter. This means it is designed to be installed in a compatible PCI expansion slot within a server or workstation. Buyers should verify that their target systems provide available PCI slots to support this adapter.

How can I uniquely identify this HP NC3134 adapter for procurement?

You can uniquely identify this adapter using both its model and SKU. The model name is HP NC3134 Fast Ethernet NIC, and the associated SKU is 138603-B21. Together with the description as a 2-port 10/100BT Fast Ethernet PCI adapter, these identifiers help ensure accurate ordering and alignment with internal part lists.
