4.2.5 Modifiable Variables

Figure 4-9. Modifiable variable.

Pressing the Enter key accepts the value displayed and advances the cursor to the next modifiable field. You can use the Up or Down key to modify the values of these fields.

If the modifiable field is a positive (+) number, the positive value is indicated by the absence of a (+) or (-) symbol. The (-) negative symbol will be displayed to the left of the first digit for negative numbers.

4.2.6 Password Authorization Levels

You can request access to a menu loop from the main menu. Modifiable control screens have variables that affect system performance. Improper settings may result in erratic operation and possible system failure or damage. Anyone is allowed direct access to the Info and Alarm log display menus with no security password.

Only authorized personnel who possess a thorough understanding of the system operation should perform modifications to secured menu settings (Control, Service, and Factory). These menus are configured with password protection, requiring a higher level of authority to access them. The screens must have accurate variables entered otherwise erratic operation may occur.

4.2.6.1 Password-Protected Screen

When you first attempt to select a secure menu in a given session, the "Enter Password” screen will be displayed. This screen displays the current security level authorized.

Figure 4-10. Enter password screen.

A session is defined as from the time access is gained to a secure menu until 60 seconds elapses with no key activity. Security access will be terminated at this point and you will have to re-enter the password to gain access. The menus that may be password-protected by the user are the Control and Service menus. The factory-level menu screens are also password-protected; however, the password is set at the factory to limit access.

Access to the Factory menu screens will only be granted while the user is working with the guidance of Black Box Technical Support (see Chapter 6), because incorrect settings made at that level could unintentionally damage the equipment. The Access ID Code in the bottom left of the “Enter Password” screen is needed when contacting Technical Support to determine the correct factory menu password for your specific controller.

The level of authority is established by entering the proper password for a given security level. The controller is shipped from the factory with preset passwords for all the security levels.

CRDX-W-FS-12KW, Black Box Cold Row DX, CRDX-W-FS-24KW, CRDX-A-FS-24KW, CRDX-A-FS-12KW specifications

The Black Box CRDX series consists of high-performance cooling solutions designed to maintain optimal temperature conditions in data centers and server rooms. Key models in this series include the CRDX-W-FS-12KW, CRDX-W-FS-24KW, CRDX-G-FS-12KW, and CRDX-A-FS-24KW. These units are engineered to provide efficient cooling while addressing the rising demands of modern IT infrastructure.

One of the standout features of the CRDX series is its cold row design. This configuration enables targeted cooling delivery directly to the equipment, enhancing efficiency and reducing energy consumption. The airflow management in these models ensures that cooled air is directed where it is needed most, minimizing hotspots and maximizing cooling performance.

Both the CRDX-W-FS-12KW and CRDX-W-FS-24KW models utilize advanced refrigerant-based cooling technology. These units are equipped with electronically commutated (EC) fans, which are highly efficient and quieter than traditional fan technologies. This innovation not only lowers operational costs but also creates a more comfortable environment within the data center.

The CRDX-G-FS-12KW model stands out for its hybrid capabilities, offering both chilled water and direct expansion cooling options. This versatility allows facility managers to choose the best cooling approach based on their specific requirements and current infrastructure. The hybrid system can optimize energy consumption and enhance cooling efficiency, contributing to lower operating costs.

Another noteworthy feature across these models is their intelligent controls and monitoring capabilities. Equipped with sophisticated sensors and control systems, operators can gain real-time insights into temperature fluctuations, humidity levels, and unit performance. This data aids in proactive maintenance and ensures that cooling systems are operating at peak efficiency.

The CRDX-A-FS-24KW, on the other hand, is designed with a focus on adaptability and scalability. This model can be integrated easily into existing network setups, making it an excellent choice for facilities that anticipate future growth or need to adapt to changing cooling demands.

Overall, the Black Box CRDX series exemplifies the latest advancements in cooling technology, offering innovative features designed to support high-density computing environments. With their efficient cooling capabilities, intelligent controls, and flexible design options, these models provide reliable solutions for data centers looking to enhance their cooling systems while reducing operating costs.
