FAQ
How many PoE+ ports does the MS125-48LP-HW have?
The MS125-48LP-HW includes 48 Gigabit Ethernet ports, all of which support Power over Ethernet Plus (PoE+). This allows you to deliver both data and electrical power to connected devices such as IP phones, wireless access points, and security cameras over standard Ethernet cables, simplifying installation and reducing the need for separate power outlets.
What types of uplink connections are supported?
This switch provides four 10 Gigabit Ethernet uplink ports that use SFP+ slots. These slots support 10GBase-X transceivers, enabling connections via optical fiber or high-speed copper cables. The uplinks are designed for aggregating traffic to core switches or servers, offering substantial bandwidth for demanding network applications.
Is this switch manageable, and how is it configured?
Yes, the MS125-48LP-HW is fully manageable through the Meraki cloud-based dashboard. Configuration, monitoring, and troubleshooting can be performed remotely via a web interface, which provides centralized control over multiple switches. Features like firmware updates, network analytics, and automated alerts are included, reducing the need for onsite IT intervention.
What layer does this switch operate at?
The MS125-48LP-HW operates at Layer 2 of the OSI model. It supports essential Layer 2 functions such as VLANs, IGMP snooping for multicast traffic optimization, port mirroring for network analysis, and spanning tree protocol to prevent loops and ensure network stability. This makes it suitable for segmenting traffic and managing local network communications.
Can this switch be mounted in a standard server rack?
Absolutely. The switch is designed with a 1U rack-mountable form factor, meaning it occupies one unit of vertical space in a standard 19-inch server rack. Its dimensions—1.73" height, 17.32" width, and 13.39" depth—ensure compatibility with most rack cabinets, and it includes mounting hardware for secure installation in data centers or network closets.
What is the power consumption of this switch?
The MS125-48LP-HW has a power consumption rating of 439.80 watts under typical operating conditions. This rating accounts for the energy required to power all 48 PoE+ ports and the switch's internal components. It is important to ensure your power infrastructure can support this load, especially when deploying multiple switches in a rack environment.
