Power Over Ethernet (PoE)

The HPE Aruba 1930 48g Switch is equipped with Power over Ethernet (PoE) technology. PoE allows the switch to provide power to connected devices such as IP phones, wireless access points, and security cameras through the Ethernet cables. This eliminates the need for separate power cables and adapters, simplifying installation and reducing clutter.

Benefits of PoE

1. Simplicity and Convenience: With PoE, you can easily deploy devices in locations where power outlets are not readily available. This flexibility allows for greater freedom in device placement and ensures a clean and organized setup.

2. Cost Savings: PoE eliminates the need for additional electrical wiring and power outlets, reducing installation costs. It also eliminates the need for separate power adapters for each device, saving on energy consumption and reducing electricity bills.

3. Scalability: PoE allows for easy expansion of your network without the need for additional power infrastructure. Simply connect your PoE-enabled devices to the switch, and they will receive both data and power over a single Ethernet cable.

Power Over Ethernet Standards

PoE is defined by several standards, including IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt. The HPE Aruba 1930 48g Switch supports both IEEE 802.3af and IEEE 802.3at standards, providing up to 30 watts of power per port.

IEEE 802.3af

The IEEE 802.3af standard delivers up to 15.4 watts of power per port, making it suitable for low-power devices such as IP phones and wireless access points.

IEEE 802.3at

The IEEE 802.3at standard, also known as PoE+, provides up to 30 watts of power per port. This higher power capacity allows for the support of power-hungry devices such as pan-tilt-zoom (PTZ) cameras and video conferencing systems.

Number Of Ports: 48

The HPE Aruba 1930 48g Switch offers a total of 48 ports, providing ample connectivity options for your network infrastructure. These ports can be used to connect various devices, including computers, servers, printers, and network switches.

Benefits of Having 48 Ports

1. Scalability: The large number of ports allows for easy expansion of your network as your business grows. You can connect multiple devices without the need for additional switches, simplifying network management.

2. Flexibility: With 48 ports, you have the flexibility to connect a wide range of devices to your network. Whether it's computers, servers, or other networking equipment, you can easily accommodate all your devices without running out of available ports.

3. Redundancy: Having multiple ports ensures redundancy in case of port failures or network congestion. You can create link aggregation groups (LAGs) to combine multiple ports into a single logical connection, providing higher bandwidth and increased reliability.

Port Types

The HPE Aruba 1930 48g Switch offers a combination of RJ-45 Ethernet ports and SFP (Small Form-Factor Pluggable) ports.

RJ-45 Ethernet Ports

RJ-45 Ethernet ports are the standard ports used for connecting devices using Ethernet cables. These ports support both data and power transmission, making them suitable for devices that require PoE.

SFP Ports

SFP ports are used for connecting devices using fiber optic cables. These ports provide high-speed connectivity and are ideal for long-distance connections or connecting to other network switches.

Number Of SFP Ports: 4

The HPE Aruba 1930 48g Switch features 4 SFP (Small Form-Factor Pluggable) ports. These ports allow for high-speed connectivity using fiber optic cables, offering greater bandwidth and longer reach compared to traditional Ethernet connections.

Benefits of SFP Ports

1. High-Speed Connectivity: SFP ports support Gigabit Ethernet and can also be used with higher-speed interfaces such as 10 Gigabit Ethernet. This enables fast data transfer rates, making them ideal for bandwidth-intensive applications or connecting to other network switches.

2. Long-Distance Connectivity: Fiber optic cables used with SFP ports offer greater distance capabilities compared to traditional Ethernet cables. This makes SFP ports suitable for connecting devices in different buildings or locations within your network infrastructure.

3. Future-Proofing: SFP ports provide flexibility and scalability for your network. You can easily upgrade your network speed by replacing or adding SFP modules without replacing the entire switch, saving costs in the long run.

SFP Modules

The HPE Aruba 1930 48g Switch supports a variety of SFP modules, allowing you to choose the most suitable module for your specific requirements. These modules include both multi-mode and single-mode options, offering flexibility in terms of distance and budget.

Multi-Mode SFP Modules

Multi-mode SFP modules are designed for short-range connections within a building or a data center. They are cost-effective and can transmit data over distances up to a few kilometers.

Single-Mode SFP Modules

Single-mode SFP modules are used for long-distance connections, such as connecting buildings or locations that are several kilometers apart. They offer higher transmission speeds and can transmit data over much longer distances compared to multi-mode modules.

Total Power Budget: 370W

The HPE Aruba 1930 48g Switch has a total power budget of 370W. This means that it can allocate a maximum of 370 watts of power across all its PoE-enabled ports.

Benefits of a High Power Budget

1. Powering Multiple Devices: With a total power budget of 370W, you can connect and power multiple PoE-enabled devices simultaneously. This allows for efficient utilization of the switch's power capabilities without compromising on performance.

2. Power Allocation Flexibility: The high power budget gives you the flexibility to allocate power according to your device requirements. You can prioritize critical devices or allocate more power to power-hungry devices, ensuring optimal performance across your network.

3. Future-Proofing: The 370W power budget provides headroom for future expansion. As your network grows and you add more PoE-enabled devices, you can rest assured knowing that the switch has the capacity to handle the increased power demands.

Power Allocation Management

The HPE Aruba 1930 48g Switch features advanced power allocation management capabilities, allowing you to monitor and control the power consumption of connected devices. This ensures efficient power usage and helps prevent overloading or power wastage.

Power Over Ethernet Plus (PoE+)

The HPE Aruba 1930 48g Switch supports the PoE+ standard, which delivers up to 30 watts of power per port. This higher power capacity is essential for powering devices that require more power, such as high-performance wireless access points or PTZ cameras.
