FAQ
How many devices can this switch power with PoE?
The switch provides 382 watts of total PoE budget across all 48 ports. This allows it to power multiple PoE+ devices simultaneously, such as IP phones, wireless access points, and security cameras. The exact number of devices depends on each device's power requirements, but the substantial budget supports typical office deployments without requiring external power injectors.
What types of SFP modules are compatible with the uplink slots?
The four expansion slots accept standard SFP (mini-GBIC) modules for Gigabit Ethernet connections. You can use either copper SFP modules for short-distance twisted-pair connections or fiber optic SFP modules for longer runs. This flexibility allows the switch to connect to existing network infrastructure using the most appropriate media type for your environment.
Is this switch manageable, and what features does it support?
Yes, this is a fully manageable Layer 2 switch. It supports essential management features including VLAN configuration for network segmentation, Quality of Service (QoS) for traffic prioritization, port security controls, and monitoring capabilities. These features provide greater control over network performance and security compared to unmanaged switches.
What is the form factor and rack mounting requirements?
The switch has a standard 1U rack-mountable form factor measuring 1.73 inches high, 17.32 inches wide, and 10.12 inches deep.
