User Manual
FAQ
What speeds do the QSFP28 ports on this switch support?
The sixteen QSFP28 ports support a range of Ethernet speeds: 1 Gigabit, 10 Gigabit, 25 Gigabit, 40 Gigabit, and 100 Gigabit. This flexibility allows you to use the same ports for different connectivity needs, from server connections to high-speed uplinks, by simply installing the appropriate QSFP28 transceivers.
How many uplink ports does this Aruba switch have?
This switch includes two SFP+ uplink ports, each supporting 10 Gigabit Ethernet. These uplinks are ideal for connecting to core switches, routers, or other aggregation points, providing high-bandwidth paths for traffic leaving the local network segment.
Is this switch capable of Layer 3 routing?
Yes, the Aruba CX 8325H is a Layer 3 switch, meaning it can perform routing functions such as inter-VLAN routing and dynamic routing protocols. This capability eliminates the need for a separate router in many scenarios, simplifying network design and improving performance for internal traffic.
What power supply configuration does this switch use?
The switch comes with two hot-swappable AC power supplies installed, supporting input voltages of 120V and 230V. This redundant configuration ensures that if one power supply fails, the other can continue to power the switch without interruption, maintaining network availability.
What is the rack unit size of this switch?
This switch has a 1U form factor, meaning it occupies one unit of vertical space in a standard 19-inch rack. Its compact design allows for high-density deployments, maximizing the number of switches you can install in a single rack while maintaining efficient back-to-front airflow.
Does this switch support stacking for network expansion?
Yes, it includes a stack port that allows you to connect multiple Aruba CX 8325H switches together, creating a single logical unit. Stacking simplifies management, increases port density, and improves resiliency by allowing for centralized configuration and redundant links across the stack.
What uplink, SFP, fiber, or media support detail is listed?
The warranty or support detail listed is Optical Fiber, giving buyers a clearer picture of expected coverage after purchase.
What management, monitoring, or control option is listed?
