Printer Server Installation 2-29

Peripheral Connections

Parallel Port

The parallel port provides a female DB25 connector and supports the following types of peripherals:

•A printer or plotter supporting a Centronics parallel port

•A printer or plotter supporting the bi-directional parallel interface (IEEE 1284)

NOTE: The parallel cable between the printer server and the printing device should not exceed 12 feet (3.65 meters).

Serial Port

Serial Port

Connect to the serial port with a null modem cable. The serial port provides a male DB9 connector and allows user to:

•Print to a serial printer or plotter.

•Monitor the printer server by connecting an ANSII compatible terminal or a PC running an ANSII terminal emulation program.

The Emulex default port configuration is set for 9600 bps, 8 data bits, no parity, 1 stop bit, DTE type, with softcopy emulation.

•Input print jobs directly by connecting to a host system serial port (e.g. an HP 3000).

It utilizes enhanced Ethernet technology to optimize network performance while reducing latency. Its support for virtualization allows for improved resource allocation, making it ideal for contemporary data center environments.

The NJ01B-NT+ complements the NQGB-NT+ with additional features aimed at improving resilience and reliability. It supports Fibre Channel over Ethernet (FCoE), which allows for the convergence of storage and data networks into a unified fabric. This not only simplifies infrastructure but also reduces overall costs and power consumption. The NJ01B-NT+ is particularly beneficial for enterprises looking to streamline their network operations while maintaining top-tier performance.

Moving on to the NQ0V-NT+, this adapter focuses on multi-protocol capabilities, enabling users to manage various network protocols within a single environment. It includes advanced features such as iSCSI offload, which enhances performance for storage area networks (SANs). Its ability to support multiple protocols makes it a versatile choice for businesses with diverse networking needs.

The NQTR0U-NATM adapter provides additional innovation by incorporating SmartNIC technology. This enables onboard processing capabilities, offloading tasks from the server CPU, which enhances overall system performance. With features that support container-based workloads and network functions virtualization (NFV), this adapter is well-suited for modern applications that require scalability and flexibility.

Finally, the NP02 module is designed with a focus on energy efficiency and high availability. It incorporates industry-leading technologies that ensure minimal downtime and optimal performance in mission-critical environments. Its advanced monitoring and management capabilities allow administrators to maintain control over their network resources, ensuring that systems run smoothly and efficiently.

Together, these Emulex network adapters deliver a comprehensive suite of features that enable businesses to optimize their network infrastructure for performance, reliability, and efficiency. With an emphasis on multi-protocol support, virtualization, and energy efficiency, Emulex products are ideal for today’s demanding data center environments. Whether for enhancing connectivity, reducing latency, or improving resource allocation, these adapters showcase Emulex's commitment to delivering high-quality networking solutions.
