How many ports are available on the HP 338456-B21 adapter?

The HP 338456-B21, identified as the Compaq NC3131 Fast Ethernet NIC, is described as a dual-port 10/100Base-T server adapter. This means the card offers two separate 10/100Base-T Fast Ethernet interfaces on a single PCI 64-bit network adapter for server connectivity.

Which expansion bus does the Compaq NC3131 Fast Ethernet NIC use?

The Compaq NC3131 Fast Ethernet NIC, SKU 338456-B21, is categorized as a PCI 64-bit Fast Ethernet NIC. This indicates that it is intended for systems with a 64-bit PCI slot, allowing the adapter to integrate into compatible servers that support that specific PCI 64-bit interface for network cards.

Is the HP 338456-B21 suitable for Fast Ethernet environments?

Yes, the HP 338456-B21 is described as the Compaq NC3131 Fast Ethernet NIC and a dual-port 10/100Base-T server adapter. As a Fast Ethernet device, it aligns with 10/100Base-T infrastructures where 10 or 100 megabit Ethernet operation is the standard for server-to-switch connections.

How can the SKU 338456-B21 help in procurement and asset tracking?

The SKU 338456-B21 uniquely identifies the HP Compaq NC3131 Fast Ethernet NIC. Using this specific SKU allows procurement teams to order the exact dual-port 10/100Base-T PCI 64-bit adapter consistently and helps asset managers distinguish it from other network adapters in inventory and configuration records.

Product overview

The HP Compaq NC3131 Fast Ethernet NIC, SKU 338456-B21, is a dual-port 10/100Base-T server network adapter designed for PCI 64-bit slots. As a Fast Ethernet NIC, it supports 10 and 100 megabit Ethernet operation to align with legacy and midrange network infrastructures that rely on 10/100Base-T connectivity. The dual-port 10/100Base-T configuration allows a single adapter to present two separate Fast Ethernet connections, supporting scenarios that need port separation or redundant links at the server level. This model is categorized as a PCI 64-bit Fast Ethernet NIC and is suitable for servers that require a dedicated 10/100Base-T network interface rather than higher speed standards. It is positioned for environments standardizing on HP and Compaq branded networking components and needing a clearly identified part number, 338456-B21, for controlled IT procurement and lifecycle management.
