We are providing specifications below to explain why you should consider purchasing the Cisco 8 Port Expansion Module Networking, including a general overview, performance specifications, relevant images, media files, and technical information about the HWIC-8A/S-232= compatibility.

More Specifications

The HWIC-8A/S-232= is a Cisco High-Speed WAN Interface Card (HWIC) that provides 8 EIA-232 asynchronous/synchronous serial ports for connecting serial devices to a Cisco router. The card is designed for use in wide-area network (WAN) environments that require serial connections for legacy equipment or for connecting to other serial devices such as modems, CSU/DSUs, and PBX systems.

The model supports both asynchronous and synchronous serial connections, which means it can handle both data formats, allowing more flexibility in connecting to different types of serial devices. The card supports data rates up to 115.2 kbps, which is sufficient for most serial devices.

The model can be installed in a Cisco router's HWIC slot, and it is supported by Cisco IOS software, which provides various features and functionalities, such as HDLC, PPP, and Frame Relay protocols, for configuring and managing the serial connections.

The card also supports SNMP (Simple Network Management Protocol) for remote management and monitoring, which means that network administrators can monitor and troubleshoot the card from a remote location.

Extraordinary Performance

The HWIC-8A/S-232= Cisco hardware interface card (HWIC) is designed to provide high performance and reliability for serial communication over EIA-232 connections.

In terms of performance, the card supports a data transfer rate of up to 230.4 Kbps per port and supports both asynchronous and synchronous serial communication, which means it can handle both types of serial data transfer. It also supports both DTE (data terminal equipment) and DCE (data communication equipment) interfaces, allowing it to connect to a wide range of serial devices. Additionally, the card supports various serial protocols, including HDLC, PPP, and Frame Relay, providing compatibility with a wide range of devices.

In terms of reliability, the card is designed with robust components and undergoes rigorous testing to ensure it can withstand harsh environmental conditions and meet the demands of high-traffic networks. It also features a hot-swappable design, which allows for easy replacement in the event of a failure, minimizing network downtime.

Additionally, the card supports the Cisco IOS software, which allows for easy management and configuration of the serial connections. It also supports the Cisco Discovery Protocol (CDP), which allows the router to automatically discover and configure connected devices, this improves the overall reliability of the network.

Compliant Standards

The model Cisco hardware interface card is compliant with a number of standards to ensure compatibility and interoperability with other network equipment. Some of the key standards that the card complies with are:

  • EIA-232: This is the standard for serial communication over a DB-25 or DB-9 connector and the HWIC-8A/S-232= card provides 8 EIA-232 ports.
  • EIA/TIA-604: This standard defines the characteristics of the physical layer interface for digital carrier systems and terminal equipment, the card is compliant with this standard, which ensures the compatibility of the card with other devices that also comply with this standard.
  • RoHS (Restriction of Hazardous Substances): This is a European Union directive that regulates the use of hazardous substances in electronic equipment. This model card is compliant with RoHS, which means it does not contain any hazardous substances that are harmful to the environment.
  • Cisco IOS software: The card is compliant with the Cisco IOS software, which allows for easy management and configuration of the serial connections, and the Cisco Discovery Protocol (CDP), which allows the router to automatically discover and configure connected devices.
  • MSA (Multi-Source Agreement): This is an industry agreement that ensures that the model card is compatible with other vendors' equipment and with other similar cards from Cisco.
