This article dives deep into the Cisco 1921 Power Consumption Datasheet, providing a clear and concise overview of what it entails and how you can leverage this vital document. The Cisco 1921 Power Consumption Datasheet is your go-to resource for all things related to the energy footprint of this popular router.
What is the Cisco 1921 Power Consumption Datasheet and How is it Used?
The Cisco 1921 Power Consumption Datasheet is a technical document that meticulously details the electrical power requirements and consumption characteristics of the Cisco 1921 Integrated Services Router. It's not just a simple number; this datasheet breaks down power usage under various operating conditions, including different configurations, module installations, and load levels. Think of it as the fuel gauge and efficiency report for your router. The importance of this datasheet cannot be overstated for network administrators, IT managers, and procurement specialists. It directly impacts decisions related to power budgeting, cooling requirements, environmental impact assessments, and overall operational expenditure.
This datasheet serves several key purposes:
- Capacity Planning: It helps determine how many Cisco 1921 routers can be powered from existing electrical circuits or power distribution units (PDUs) without overloading them.
- Cooling Strategy: Higher power consumption translates to more heat generation. The datasheet informs the design of appropriate cooling solutions for server rooms and data centers to prevent overheating.
- Cost Analysis: By understanding the power draw, organizations can accurately estimate electricity costs associated with operating these routers over their lifecycle.
- Environmental Responsibility: For organizations with sustainability goals, the datasheet provides data to calculate the carbon footprint of their network equipment.
The information within the Cisco 1921 Power Consumption Datasheet is typically presented in a structured format. You'll often find:
| Parameter | Description |
|---|---|
| Typical Power Consumption | The average power drawn during normal operation. |
| Maximum Power Consumption | The highest power draw, often under full load or with all optional modules installed. |
| Standby Power Consumption | The power used when the router is idle or in a low-power state. |
| Power Supply Specifications | Details about the AC or DC power supplies used, including voltage and amperage ratings. |
Furthermore, the datasheet often includes specific values for different configurations. For instance, it might detail power consumption with various network interface modules (NIMs), service modules (SMs), or when specific features like encryption acceleration are enabled. A numbered list might detail the power draw for each specific module, allowing for precise calculation based on the deployed hardware. For example:
- Base router (no modules): X Watts
- Router with one Gigabit Ethernet module: Y Watts
- Router with two Gigabit Ethernet modules and a security module: Z Watts
This granular detail is essential for accurate planning.
We encourage you to refer to the official Cisco 1921 Power Consumption Datasheet for the most accurate and up-to-date figures relevant to your specific deployment. This document is your authoritative source for making informed decisions about your network's power requirements.
