During the PRECOOL stage the TIME REMAINING line counts down the time for that stage in 5-second increments: 4:45, 4:40, 4:35, etc.

After the PRECOOL stage comes the first GRINDING stage, and the screen displays STATUS: GRINDING. The TIME REMAINING line will display the time left in that grinding stage. If there are 3 grinding periods, during the first one the CYCLES REMAINING line will display 3 OF 3, during the second the CYCLES REMAINING line will display 2 of 3, etc. In every stage the TIME REMAINING line will count down the time left in that stage in 5-second increments.

For example, if you were running the program on the CURRENT SETTINGS screen displayed on page 8, and you were 15 seconds into the second grinding period, this is what the STATUS screen would display:

STATUS: GRINDING

Time Remaining: 1:45

Cycles Remaining: 2

RATE: 10 -----------

STATUS SCREEN during a run

Between any two grinding periods is the COOL DOWN stage, displayed as STATUS: COOL DOWN.

When the grinding program is complete, the START screen will display STATUS: RUN

COMPLETE, TIME REMAINING: 0:00, and (in the case of the program displayed on page 8)

CYCLES REMAINING: 0 OF 3.

While in the STATUS screen, the only parameter you can change is the RATE. It is changed by touching the slider (I) and moving it to the left or right. Moving the slider to the left decreases the rate. Moving it to the right increases the rate. As the rate changes, the number in the display will change. Rate is the number of back-and-forth cycles per second of the impactor. Since the

6870 specifications

The Allied Telesis 6870 is a robust Layer 3 Ethernet switch designed for high-performance networking in enterprise environments. Incorporating advanced features and technologies, it serves as a vital component in managing complex network infrastructures, ensuring seamless connectivity, reliability, and enhanced performance.

One of the standout characteristics of the 6870 is its support for a high number of Gigabit Ethernet ports. With multiple SFP and SFP+ ports, the switch allows for flexibility in connecting various devices, while also facilitating the use of different physical media. This capability is crucial for organizations that demand versatile connection options, particularly when managing diverse networking equipment.

The switch is equipped with advanced Layer 3 routing capabilities, allowing it to perform IP routing functions in addition to standard Ethernet switching. Suitable for traffic management, the switch supports protocols such as OSPF, RIP, and static routing, enabling efficient and intelligent path selection in larger networks. This functionality is essential for optimizing bandwidth usage and maintaining an efficient data flow throughout the network.

Another highlight of the Allied Telesis 6870 is its support for VLANs (Virtual Local Area Networks). VLANs enable network segmentation, improving security and performance by isolating different segments of traffic. This capability is further enhanced by the switch's support for advanced features like Ingress/Egress Rate Limiting and Quality of Service (QoS). These features allow network administrators to prioritize critical applications and ensure that bandwidth is allocated effectively.

The switch also incorporates the innovative Allied Telesis Autonomous Management Framework (AMF), which simplifies device management and network configuration. With AMF, administrators can manage multiple switches as a single logical entity, reducing operational complexity and minimizing downtime. This technology supports zero-touch provisioning, enabling rapid deployment and configuration of network devices.

Security is another key aspect of the 6870, with features such as Access Control Lists (ACLs) and IEEE 802.1X port-based authentication. These measures help protect the network from unauthorized access and ensure that only authenticated devices can connect to the network.

In summary, the Allied Telesis 6870 is a versatile and powerful switch that meets the demands of modern enterprise networks. With its comprehensive feature set, including high-performance routing, VLAN support, and advanced management capabilities, it offers a reliable solution for organizations seeking to optimize their network infrastructure. Whether for deploying new services or managing existing traffic, the 6870 stands out as a formidable choice for network administrators.
