C9800-L-F-K9 có những đặc điểm nào giúp tiết kiệm không gian và điện năng trong trung tâm dữ liệu?
C9800-L-F-K9 sử dụng thiết kế 1RU half-width, cho phép lắp hai thiết bị trên cùng một không gian rack 1RU tiêu chuẩn. Thiết bị có mức tiêu thụ điện tối đa chỉ 84,5 W, công suất tỏa nhiệt 288,2 BTU/hr và độ ồn chỉ 40 dBA trong điều kiện hoạt động bình thường, giúp tiết kiệm không gian lắp đặt, điện năng và chi phí vận hành trong trung tâm dữ liệu hoặc phòng máy.
C9800-L-F-K9 hỗ trợ những phương thức triển khai nào để phù hợp với nhiều mô hình mạng khác nhau?
C9800-L-F-K9 hỗ trợ ba chế độ triển khai gồm Centralized, Cisco FlexConnect và Fabric Wireless (SD-Access). Nhờ đó, thiết bị có thể triển khai linh hoạt cho hệ thống mạng tập trung, các chi nhánh từ xa hoặc môi trường sử dụng kiến trúc SD-Access để tăng khả năng tự động hóa, mở rộng và quản lý tập trung.
C9800-L-F-K9 có ưu điểm gì khi sử dụng cổng quang SFP+ thay vì cổng đồng?
C9800-L-F-K9 được trang bị 2 cổng uplink quang 10G SFP+ cùng 4 cổng đồng 2.5G/1G, hỗ trợ nhiều module quang như SFP-10G-SR, SFP-10G-LR, SFP-10G-LRM và các module Finisar tương thích. Thiết kế này giúp thiết bị dễ dàng kết nối với hệ thống Core Switch qua cáp quang, đáp ứng yêu cầu truyền dữ liệu tốc độ cao trên khoảng cách xa và giảm nhiễu điện từ trong môi trường doanh nghiệp.
