Question

You have an equipment rack in your datacenter that has the following installed: 4 x Cisco Catalyst c9200-24T switches, 1 x Cisco Catalyst 9606R core switch, 2 x Cisco 2811 routers, and 1 SonicWall TZ270. How much power will this stack use? What UPS would you choose to support this stack? (research required)

Answer 1

To calculate the total power consumption of the equipment rack, we need to consider the power requirements of each device. Here are the power consumption values for the given equipment:

- Cisco Catalyst c9200-24T switch: The power consumption of each switch is approximately 53 watts.

- Cisco Catalyst 9606R core switch: The power consumption of the core switch is around 670 watts.

- Cisco 2811 routers: Each router consumes around 90 watts.

- SonicWall TZ270: The power consumption of the TZ270 is approximately 15 watts.

To calculate the total power consumption, we add up the power requirements of all the devices:

(4 switches x 53 watts) + 670 watts + (2 routers x 90 watts) + 15 watts = total power consumption.

Now, let's calculate the total power consumption:

(4 x 53) + 670 + (2 x 90) + 15 = 212 + 670 + 180 + 15 = 1077 watts.

Therefore, the stack will use approximately 1077 watts of power.

For choosing the UPS (Uninterruptible Power Supply) to support this stack, we need to consider the power requirements and the runtime needed during a power outage. The UPS should be able to supply enough power to keep the equipment running for a desired amount of time.

To select an appropriate UPS, you should consider factors such as the capacity (measured in volt-amperes or VA), the runtime, and any additional features required (such as monitoring and management capabilities).

The UPS capacity should be equal to or greater than the total power consumption of the stack. In this case, a UPS with a capacity of at least 1077 VA or higher would be suitable.

Additionally, the desired runtime during a power outage should also be taken into account. This depends on factors such as the criticality of the equipment and the availability of backup power sources. You may want to estimate how long the UPS needs to provide power to the equipment until the power is restored or alternate power sources are activated.

Remember to check the product specifications and consult with a professional or the manufacturer to ensure the chosen UPS meets the power requirements and runtime needs of the equipment stack.

Overall, the total power consumption of the equipment rack is approximately 1077 watts. To support this stack, you would need to choose a UPS with a capacity of at least 1077 VA and consider the desired runtime during a power outage.

Answer 2

To calculate the power usage of the equipment rack, we need to find the power consumption of each device and add them together. Unfortunately, we do not have the power consumption information for the Cisco 2811 routers and the SonicWall TZ270. However, we can estimate the power consumption of the Cisco Catalyst switches based on their specifications. According to the Cisco Catalyst c9200-24T switches have a maximum power consumption of 250 watts each, and the Cisco Catalyst 9606R core switch has a maximum power consumption of 4,000 watts. Therefore, the total power consumption of the switches and core switch is:

4 x 250 watts + 1 x 4,000 watts = 5,000 watts

To choose the appropriate UPS to support this stack, we need to select a UPS with a power rating that is greater than or equal to the total power consumption of the equipment rack. Based on the power consumption calculated above, we should choose a UPS with a power rating of at least 5,000 watts. However, we also need to consider other factors such as the runtime required during a power outage, the number of outlets needed, and the type of UPS (online, line-interactive, or standby). Therefore, we recommend consulting with a qualified electrician or IT professional to select the appropriate UPS for this equipment rack
