Can I mix copper and fiber connections on this switch?

Yes. Four of the 24 ports are dual-purpose, functioning as either standard RJ-45 10/100/1000 or SFP Gigabit interfaces. Additionally, one expansion module slot accommodates 8-port SFP modules or 2-port 10-Gigabit modules, enabling flexible mixed-media deployments without replacing the core switch.

How many switches can I stack, and what is the total port count?

Up to eight 5500G-EI units can stack via XRN fabric ports, managed as a single entity. This delivers up to 448 total Gigabit ports (8 units × 56 ports including expansion slots) with centralized management, reducing operational overhead and enabling consistent policy enforcement.

What management protocols does the 5500G-EI support?

The Enhanced Image (EI) software supports SNMP for remote monitoring, NTP for time synchronization, DHCP Relay for distributed IP assignment, and configuration backup/restore capabilities. Layer 3 routing enables advanced traffic prioritization and security policies for converged network environments.

What is the switching capacity and forwarding rate?

Base configuration delivers 192 Gbps switching capacity with 107.1 Mpps forwarding rate. With optional 2-port 10-Gigabit module, capacity expands to 184 Gbps and 136.9 Mpps. All 24 ports operate at wirespeed 10/100/1000 Mbps, ensuring zero-loss switching for simultaneous multi-port traffic.

Is the 5500G-EI suitable for data center deployments?

Yes. The 1U rack-mountable form factor, 192 Gbps switching capacity, Layer 3 intelligence, and stackable architecture make it ideal for enterprise data centers. Enhanced Image software supports 99.999% uptime requirements, and the expandable design accommodates future growth without infrastructure replacement.

What power consumption should I plan for?

The 24-port PWR model consumes 109W base power plus up to 300W for PoE delivery, totaling approximately 409W maximum. Input voltage is 90-240 VAC at 50/60 Hz with 8.0A maximum AC current rating. External RPS (Redundant Power Supply) support accommodates up to 9000W with six rectifiers for high-availability deployments.
