SKYRS ensures that all 3650-48PS-S variants are equipped with modular components to handle the varied environmental and electrical conditions found in Pakistan.
WS-C3650-48PS-S (Base): 48-port PoE+ chassis with 4 x 1G SFP uplinks and a 640WAC default power supply.
Secondary PSU Support: Provision for a second PWR-C2-640WAC or 1025WAC power supply to provide 1+1 redundancy or increase the PoE budget.
Stacking Hardware: C3650-STACK-KIT is available to group up to 9 switches into a single logical unit with a single management IP.
Modular Cooling: Three field-replaceable fan modules are included to maintain thermal integrity.
SKYRS provides specialized on-site physical installation services across Pakistan, ensuring that hardware is deployed following manufacturer-validated designs and local safety standards.
Physical Installation Steps:
Rack Integration: Secure 1U rack-mount installation with optimal spacing for thermal management in standard 19-inch racks.
Power Redundancy Setup: Configuration of dual power feeds to ensure high availability during local power fluctuations.
Stacking Implementation: Physical connection of StackWise-160 cables in a ring topology for maximum throughput and hitless failover.
Structured Cabling: High-quality copper termination for 48 ports and fiber-optic uplink verification.
Configuration of the 3650-48PS-S is performed exclusively by SKYRS certified engineers to leverage the advanced Layer 3 features of the IP Base license.
Configuration Services Include:
Advanced Layer 3 Routing: Implementation of OSPF (stub), EIGRP (stub), and Static routing for efficient inter-VLAN communication.
Wireless Provisioning: Setting up the integrated wireless controller to manage up to 25 Access Points and 1000 wireless clients.
Security Hardening: Implementation of Port Security, DHCP Snooping, Dynamic ARP Inspection (DAI), and 802.1x authentication.
Quality of Service (QoS): Prioritizing voice and video traffic to ensure clear communication over the PoE-powered VoIP infrastructure.
As of April 2026, the Cisco Catalyst 3650 series has reached its final lifecycle milestones.
SKYRS Support Advisory: The official Last Date of Support (LDoS) for the 3650-48PS-S is October 31, 2026. SKYRS provides full configuration and physical installation support until this date. For long-term network roadmaps, we recommend consulting our team regarding a transition to the Cisco Catalyst 9300L series for continued security updates and modern software-defined features.
