An inventory refresh involving discontinued SG350-52-K9-UK equipment has a named migration relationship to this model. Retain the existing configuration as a migration reference rather than assuming unchanged settings. Record endpoint assignments, uplink media and administrative access requirements before specifying the replacement order.
A multi-site rollout can use text-editable configuration files to prepare repeatable settings before shipment. Separate shared settings from site-specific addressing and credentials, and assign responsibility for configuration approval. Include the staging configuration and local installation requirements with the purchase order rather than relying on verbal handover.
10G connections to distribution
The fixed uplinks operate at 1G. C1300-48T-4X provides four 10G SFP+ uplinks while retaining 48 Gigabit copper access ports.
Switch-powered phones or access points
The copper ports do not deliver PoE. C1300-48P-4G provides endpoint power delivery with 48 Gigabit access ports and four 1G SFP uplinks.
A unified hardware switch stack
CBS350-48T-4G-UK does not support hardware stacking. Centralized management does not turn separate switches into a shared forwarding and control system.
