User Manual
FAQ
What speeds do the QSFP28 ports support?
Each of the 16 QSFP28 ports supports auto-negotiation across multiple Ethernet speeds: 1 Gigabit, 10 Gigabit, 25 Gigabit, 40 Gigabit, and 100 Gigabit. This flexibility allows the switch to connect to a wide range of devices, from legacy 1G equipment to modern 100G servers and storage, without requiring port-specific hardware changes.
What is the significance of back-to-front airflow?
Back-to-front airflow is a cooling design where the switch draws cool air from the front of the rack and exhausts hot air to the rear. This aligns with standard data center hot aisle/cold aisle configurations, improving thermal efficiency and reducing cooling costs in dense deployments. It ensures consistent operation in environments with controlled airflow management.
How many power supplies are included and are they redundant?
The switch includes two hot-swappable power supplies installed by default. It supports redundant power operation, meaning if one power supply fails or is removed for maintenance, the other can continue to power the switch uninterrupted. This design enhances reliability for critical data center applications.
What management features does this switch offer?
This is a fully manageable Layer 3 switch with features like intelligent monitoring, Virtual Extensible LAN (VXLAN) for network virtualization, Synchronous Ethernet (SyncE) for timing synchronization, and Remote Monitoring (RMON). It includes multiple management ports: RJ-45 console, USB Type-C console, RJ-45 management, and USB Type A AUX for flexible administrative access.
What rack space does this switch require?
The switch has a 1U form factor, meaning it occupies one rack unit of height in a standard 19-inch rack. Its compact, rack-mountable design makes it space-efficient for high-density deployments. The back-to-front airflow is compatible with typical rack cooling layouts.
What does TAA compliance mean for this switch?
TAA (Trade Agreements Act) compliance indicates that the switch meets U.S. government procurement requirements for products to be manufactured or substantially transformed in designated countries. This makes it suitable for government, public sector, and other contracts that mandate TAA-compliant networking equipment.
What uplink, SFP, fiber, or media support detail is listed?
The warranty or support detail listed is Optical Fiber, giving buyers a clearer picture of expected coverage after purchase.
What management, monitoring, or control option is listed?
Gigabit Ethernet,10 Gigabit Ethernet,25 Gigabit Ethernet,40 Gigabit Ethernet,100 Gigabit Ethernet.
