3. Usage Features
4. Maintenance Features

The Cisco Meraki MS125 series is a line of cloud-managed Layer-2 Gigabit Ethernet switches designed for various network environments, from small businesses to larger enterprises. These switches offer a range of port configurations and Power over Ethernet (PoE) capabilities, making them versatile for different deployment needs.

Function Description:

The MS125 series switches provide Layer-2 switching functionality, enabling efficient data forwarding within a local area network. As cloud-managed devices, they integrate seamlessly with the Meraki dashboard, offering centralized control, monitoring, and troubleshooting from any location with internet access. This cloud-based management simplifies network deployment and ongoing maintenance, eliminating the need for on-site controllers. Key functions include port management, VLAN configuration, quality of service (QoS) settings, and security features. The PoE-capable models (MS125-24P, MS125-48LP, MS125-48FP) can power connected devices such as IP phones, wireless access points, and security cameras directly over Ethernet cables, reducing cable clutter and simplifying power infrastructure. The switches also feature SFP+ interfaces for high-speed uplinks, supporting 10 Gigabit Ethernet connections to other switches or network devices.

Usage Features:

The MS125 series is designed for ease of use and flexible deployment.

• Cloud Management: All configuration, monitoring, and troubleshooting are performed through the Meraki dashboard. This allows for remote management, zero-touch provisioning, and automated firmware updates.
• Installation: The switches are 1U rack-mountable. The package includes mounting screws and cage nuts (US 12-24, INTL M5, INTL M6) and mounting washers. An optional MA-MNT-MID-1 mid-mount bracket is available for 48-port models when using 2-post racks.
• IP Address Assignment: Switches can be assigned IP addresses dynamically via DHCP or statically. For static assignment, users can connect a client machine to the switch, access its built-in web server (http://my.meraki.com or http://1.1.1.100), and configure the IP address, net mask, gateway, and DNS servers through the "Uplink Configuration" tab. DHCP reservations are also supported for assigning static IPs via the upstream DHCP server.
• Status Indicators:
  • Power LED: Solid orange indicates the switch is unable to connect to the Meraki cloud. Flashing white means a firmware upgrade is in process. Solid white signifies the switch is fully operational and connected to the Meraki cloud. Off means no power.
  • Switch Port LEDs: Off indicates no link detected. Flashing orange (RJ45 ports only) is an activity indicator. Solid green signifies a 1 Gbps link detected.
  • Management Interface LED: Green indicates connected, used for easy access to the local status page.
• PoE Capabilities: PoE models provide power to connected devices, simplifying network infrastructure for IP phones, wireless access points, and other PoE-enabled devices.
• SFP+ Uplinks: The 10GbE SFP+ ports allow for high-bandwidth connections, crucial for aggregating traffic from multiple access switches or connecting to core network devices.

Maintenance Features:

The MS125 series incorporates features to simplify maintenance and troubleshooting.

• Cloud-Based Monitoring: The Meraki dashboard provides real-time visibility into switch performance, port status, and connected devices, enabling proactive identification and resolution of issues.
• Firmware Updates: Firmware upgrades are managed automatically through the Meraki cloud, ensuring the switches always run the latest software with minimal manual intervention.
• Factory Reset Button: A RESTORE button is available on the front panel.
  • A brief, momentary press deletes the downloaded configuration and reboots the unit.
  • Pressing and holding for more than 10 seconds forces a full factory restore, returning the unit to its original factory settings.
• Basic Troubleshooting: The guide suggests basic troubleshooting steps such as checking cables, testing cables on another device, and performing a factory reset.
• Cisco Meraki Support: If hardware issues persist, users can contact Cisco Meraki support through the dashboard's Help option for assistance, including opening an email case or calling.
• Warranty: The MS125 switches come with a lifetime warranty. Accessories (SFP Modules, twinax/SFP+ cables, stacking cables, mounting kits, stands, antennas, interface modules, additional power cords, PoE injectors) have a 1-year warranty. Hardware replacement under warranty requires access to the original packaging, which includes the device serial number and order information.
