How many Ethernet ports does the HP 374161-B21 provide?

This model is described as a 1 x Port RJ-45 Network Adapter, meaning it provides one physical RJ-45 Ethernet port. The single-port design is useful for devices that only need one wired Ethernet connection, simplifying port assignments and cabling compared to multi-port network adapters.

Which Ethernet speed categories is the HP 374161-B21 aligned with?

The adapter is listed under the single-port RJ-45 10, 100, 1000 Mbps category. This aligns it with Ethernet networks that operate at traditional 10 Mbps, 100 Mbps, or 1000 Mbps speeds, allowing deployment across a range of network segments that use copper RJ-45 connectivity.

What interface category does the HP 374161-B21 belong to?

The HP 374161-B21 falls under the Gigabit Ethernet PCI Network Adapter category. This indicates that it is intended for use in systems that support PCI network cards and operate within Gigabit Ethernet–class environments, helping IT teams match it to compatible platforms and performance tiers.

Is the HP 374161-B21 suitable for environments standardizing on RJ-45 cabling?

Yes, the model name explicitly defines it as a 1 x Port RJ-45 Network Adapter and it is categorized as single-port RJ-45 10, 100, 1000 Mbps. This makes it appropriate for infrastructures that use standard RJ-45 copper cabling and require a single wired Ethernet port per device.
