Description
Performance of 20 Ports Expansion Module
With PoE support, the J9548A module can provide power to connected devices without the need for an external power source. This simplifies the deployment of devices, as it reduces the number of cables and power outlets required.
The amount of power that can be delivered to a device is determined by the PoE standard that the device supports. The J9548A module supports the 802.3at standard, which can deliver up to 30W of power per port. This allows the module to power high-power devices such as access points with multiple radios or cameras with pan-tilt-zoom functionality.
It is important to note that not all ports on the J9548A module support PoE. It is important to check with HPE or its authorized resellers for the specific PoE capabilities of the J9548A module.
Power over Ethernet Support
The J9548A is a network module that provides 20 Gigabit Ethernet ports and 2 SFP+ ports for fiber connectivity to the HPE ProCurve and HPE FlexNetwork switch families. It allows for high-speed data transfer and fiber connectivity, but it does have the capability to provide power to the connected devices. This means that devices that require power will need to have an external power source.
Power over Ethernet (PoE) is a standard that allows power to be delivered over an Ethernet cable to devices such as IP phones, wireless access points, and other PoE-enabled devices. This can simplify the deployment of these devices by reducing the number of cables and power outlets required. However, the J9548A module support PoE technology, so devices connected to it will receive power over the Ethernet cable.
It’s important to note that all devices need PoE, some devices have their own power source, in this way the J9548A module can still be used to connect and transfer data to those devices without PoE support. Additionally, the switch it’s used with may support PoE in other ports or even in other modules, so it’s important to check the switch and its capabilities to know if PoE is needed in the network.
Scalability and Upgradability
The J9548A HPE Expansion Module is designed to provide scalability and upgradability to the HPE ProCurve and HPE FlexNetwork switch families. It allows for the addition of additional Ethernet ports and fiber connectivity as the organization’s network needs grow.
- Scalability: The module can be added to the switch as needed to provide additional ports and fiber connectivity, allowing for scalability as the organization’s network needs grow. This allows for easy expansion of the network without the need for costly switch upgrades.
- Upgradability: The module is designed to be easy to install and replace, which allows for easy upgrades to the network infrastructure. This makes it simple to upgrade or repair the network when required.
It’s important to note that the scalability and upgradability of the module is dependent on the switch it will be used with. It’s important to check with HPE or its authorized resellers for the specific scalability and upgradability of the J9548A module and its compatibility with the target switch.
