User Manual
FAQ
How many devices can this switch power with PoE?
The switch has a total PoE budget of 370 watts, which it can allocate across its 48 Gigabit Ethernet ports. The exact number of devices it can power depends on the power requirements of each connected PoE or PoE+ device. For example, it could power numerous lower-power devices like IP phones (typically 3-7W each) or a mix of higher-power devices like wireless access points (often 15-30W each). The switch supports both IEEE 802.3af (PoE) and 802.3at (PoE+) standards.
What are the uplink options on this Aruba switch?
This switch includes four SFP+ expansion slots that support 10 Gigabit Ethernet connections (10GBase-X). These slots can be used with compatible SFP+ transceivers for optical fiber connections or with direct-attach copper cables. These uplinks are designed for connecting to core switches, servers, or other high-bandwidth network segments, providing increased throughput and reducing potential bottlenecks in your network architecture.
Is this switch manageable, and what management features does it offer?
Yes, this is a smart managed switch. It offers Layer 2 management features through a web-based interface or mobile app, allowing for configuration of VLANs (IEEE 802.1Q), quality of service (IEEE 802.1p), link aggregation, and port-based access control (IEEE 802.1x). It also includes auto Denial of Service prevention and supports various networking protocols for a controlled and secure network environment, making it more capable than an unmanaged switch but less complex than a fully enterprise-managed switch.
Can this switch be mounted in a standard equipment rack?
Yes, the switch is designed for 1U rack mounting in a standard 19-inch equipment rack. Its dimensions are 1.73" (43.90 mm) high, 17.42" (442.50 mm) wide, and 12.70" (322.60 mm) deep, which fits the 1U space specification. It also offers alternative mounting options including wall mounting, tabletop placement, cabinet mounting, or under-table installation, providing flexibility for various deployment environments.
What is the maximum data transfer rate of this switch?
The switch has a maximum data transfer rate of 1.25 gigabytes per second (GB/s). This throughput capacity supports the aggregate traffic across its 48 Gigabit Ethernet ports and four 10 Gigabit SFP+ uplinks, ensuring efficient data handling for business applications, file transfers, and multimedia traffic without performance degradation under typical loads.
Does this switch support fiber optic connections?
Yes, the switch supports optical fiber connections through its four SFP+ slots. By installing compatible SFP+ fiber transceivers, you can connect the switch to other fiber-enabled network devices using fiber optic cables. This allows for longer distance connections (beyond the 100-meter limit of copper Ethernet) and can provide immunity to electromagnetic interference, making it suitable for connections between buildings or across large facilities.
