Deployment and Installation Guide
SKYRS provides specialized end-to-end deployment services across Pakistan. The installation process follows Cisco’s best practices for thermal management and structural integrity.
Physical Installation
Rack Mounting: The switch occupies 1RU in a standard 19-inch rack. Brackets should be secured using the provided M4 screws before mounting into the chassis.
Airflow Management: Ensure at least 10cm of clearance around the intake and exhaust fans. The SG550XG uses smart fans that adjust speed based on the ambient temperature (0°C to 50°C).
Power Redundancy: For high-availability deployments at SKYRS, it is recommended to connect the RPS (Redundant Power System) connector to an external power source to prevent downtime during internal PSU failure.
Cabling Requirements
10G Copper: Requires Category 6A or higher UTP cables for distances up to 100 meters.
10G Fiber: Use SFP+ modules (SR for short-range, LR for long-range) with appropriate LC patch cords.
Configuration Availability at SKYRS
The configuration of these units is handled by SKYRS certified engineers using either the Graphical User Interface (GUI) or the Command Line Interface (CLI).
Initial Configuration Steps
Default Access: The default management IP is 192.168.1.254.
Out-of-Band (OOB) Management: Use the dedicated OOB port for management traffic to separate it from the data plane, enhancing security and accessibility.
Stacking Setup: Configure the stacking mode (Native or Hybrid) via the stack configuration command or the Web UI to synchronize the control plane across multiple units.
Security and Advanced Features
VLAN Segmentation: Support for up to 4,094 active VLANs for network isolation.
