User Manual
FAQ
How many devices can I connect to this switch chassis?
The Aruba CX 5420 chassis provides 24 Gigabit Ethernet ports for connecting network devices. Additionally, the six expansion slots allow for adding line cards that can increase port count beyond the base 24 ports, depending on the specific line cards installed.
Does this switch support Power over Ethernet?
Yes, all 24 Gigabit Ethernet ports support Power over Ethernet (PoE). The chassis is compliant with IEEE 802.3bt standards, which enables delivery of higher power levels to compatible devices such as advanced wireless access points, pan-tilt-zoom cameras, and thin clients.
What is the difference between Layer 2 and Layer 3 switching?
Layer 2 switching operates at the data link layer, forwarding traffic based on MAC addresses within a single broadcast domain. This Aruba CX 5420 chassis supports Layer 3 switching, which adds routing capabilities at the network layer, allowing traffic forwarding between different IP subnets and VLANs without requiring external routers.
How do the expansion slots work on this modular chassis?
The six expansion slots accept Aruba line cards that add specific port types and densities to the chassis. You can install additional copper Ethernet ports, fiber optic interfaces, or combination cards. These line cards are hot-swappable, meaning they can be inserted or removed while the chassis is powered on and operating.
What rack space does this switch require?
This chassis occupies 4 rack units (4U) of vertical space in a standard 19-inch equipment rack. The dimensions are 1.69 inches high, 8.39 inches wide, and 9.02 inches deep. It includes mounting hardware for secure installation in data center racks or network closet enclosures.
Can this switch operate with redundant power?
Yes, the chassis supports up to four power supplies with redundancy capabilities. You can install multiple power supplies to create N+1 or N+N redundancy configurations, ensuring continuous operation if one power supply fails. The power supplies are hot-swappable for maintenance without interrupting network services.
