How many powered devices can the 2910al-48G-PoE+ support simultaneously?

The switch provides 375 watts total PoE+ budget with up to 30 watts per port. This supports approximately 12-15 high-power devices (30W each) or significantly more lower-power devices like IP phones (15W) or wireless access points (20W). Dynamic power allocation via LLDP-MED optimizes distribution based on actual device requirements.

Can this switch route between VLANs without a separate router?

Yes. The 2910al-48G-PoE+ includes Layer 2 plus Layer 3 lite functionality with static IP routing and RIP 1/2 support. This enables inter-VLAN routing and basic dynamic routing capabilities. However, for complex routing scenarios, a dedicated Layer 3 switch or router is recommended.

What are the uplink options for connecting to core network infrastructure?

The switch includes 4 dual-personality ports supporting either RJ45 10/100/1000 or mini-GBIC connectivity. Additionally, up to 4 optional 10-Gigabit ports can be added using CX4 copper or SFP+ fiber modules, providing flexible uplink capacity for core connectivity.

What management protocols and monitoring capabilities are supported?

Management includes SNMP for remote administration, sFlow for traffic monitoring, ACLs for access control, and LLDP-MED for dynamic power allocation. The switch also supports IPv6 host and dual stack configurations. Serial console port provides out-of-band management access.

How does the switch ensure high availability and reliability?

The 2910al-48G-PoE+ features dual flash images for independent primary and secondary OS files, enabling backup and recovery. Redundant Power Supply (RPS) input port and External Power Supply (EPS) input port support redundant power configurations. These features minimize downtime during maintenance or failures.

What is the physical form factor and rack mounting requirements?

The switch is a 1U rack-mountable device with dimensions of 36.58cm (D) x 44.25cm (W) x 4.39cm (H). It integrates seamlessly into standard 19-inch server racks, making it suitable for data center and network closet deployments with minimal space requirements.

How many MAC addresses and routing table entries does the switch support?

The 2910al-48G-PoE+ supports 16,000 MAC address table entries and 2,000 routing table entries. These capacities support large-scale enterprise deployments with hundreds of connected devices and multiple subnets without performance degradation.
