What network type and speeds does the HP 133749-B21 adapter support?

The HP 133749-B21 is a 16/4 Token Ring PCI Network Interface Card designed for Token Ring networks. It supports operation at 16 Mbps and 4 Mbps, aligning with traditional Token Ring infrastructure. This makes it suitable for environments that maintain Token Ring segments at either of these legacy speeds and require compatible network adapters.

Which system bus interface is required for the HP 16/4 Token Ring card?

This adapter is a PCI Network Interface Card, so it requires a system with available PCI expansion slots. The PCI interface allows the card to connect directly to the system’s internal bus. Procurement teams should verify that target servers or workstations support PCI slots before planning deployment of the 133749-B21.

: "Does the HP 133749-B21 support Wake-on-LAN functionality?

Yes, the card is listed under the category 16/4 Mbps with Wake-on-LAN, indicating that it includes Wake-on-LAN capability. This allows systems using the adapter to be remotely powered on or awakened over the network. Such functionality is useful for remote management and maintenance in Token Ring-based environments.

How should I reference this adapter for procurement and documentation?

For purchasing and internal documentation, you should reference the SKU 133749-B21 along with the full product name HP 16/4 Token Ring PCI Network Interface Card. Using the precise SKU helps avoid confusion with other HP network adapters and ensures consistent configuration across orders and asset records.

Is the HP 16/4 Token Ring PCI card suitable for maintaining legacy networks?

The HP 16/4 Token Ring PCI Network Interface Card is suited to environments that still operate Token Ring networks at 16 and 4 Mbps. It provides Token Ring connectivity through a PCI interface and is categorized as a 16/4 Mbps Token Ring NIC with Wake-on-LAN. This makes it relevant for maintaining or supporting legacy Token Ring infrastructures.
