User Manual
FAQ
What is the primary purpose of the 32 expansion slots on this switch?
The 32 QSFP28 expansion slots provide high-density 100 Gigabit Ethernet connectivity for data center environments. These slots enable connections to servers, storage systems, and other network equipment using either optical fiber for long-distance runs or direct-attach copper cables for shorter connections within racks.
How does the back-to-front airflow design benefit installation?
The back-to-front airflow matches standard data center cooling configurations where cold air enters from the front of racks and hot air exhausts from the back. This design ensures efficient thermal management when installed in typical rack environments, maintaining optimal operating temperatures for reliable performance.
What Layer 3 capabilities does this switch provide?
As a Layer 3 managed switch, it supports advanced routing functions including inter-VLAN routing, static routing, and dynamic routing protocols. These capabilities enable network segmentation, improved traffic management, and enhanced security through policy-based routing decisions at wire speed.
Can this switch be stacked with other Extreme Networks switches?
Yes, the switch includes a stack port that enables stacking with compatible Extreme Networks switches. Stacking simplifies management by treating multiple physical switches as a single logical device, providing unified configuration, monitoring, and redundancy across the stack.
What types of network media are supported?
The switch supports both optical fiber and twisted pair (copper) media. Optical fiber connections enable longer distance runs between equipment, while twisted pair connections provide cost-effective connectivity for shorter distances within data centers or wiring closets.
What are the rack mounting specifications?
The switch has a standard 1U rack-mountable form factor measuring 1.70" in height, 17.30" in width, and 22.44" in depth. It weighs approximately 16.30 lb and uses standard rack mounting hardware. The dimensions comply with EIA-310-D standards for 19-inch rack compatibility.
