When qualifying replacement stock for an installed fleet, affected WS-C3750G-12S-E units can fail to boot after a power cycle under FN63745. Specify inspection, power-on and POST testing, and clean-boot verification; include the required condition and quantity before issuing the purchase order.
When an installed fleet needs regional replacement stock, ORM supports stock and RMA handling across the UK, EU, US, and MEA. Define the spare quantity, delivery region, and advance-replacement requirement together so the purchase order identifies the commercial handling required for each location.
Power delivery to connected endpoints
WS-C3750G-12S-E does not provide PoE, so endpoints requiring power through their network connection need a separate power source or a different switch.
Active Cisco hardware support
Cisco support ended January 31, 2018. C9300-24S-A is a current migration option with 24 SFP ports, rather than twelve, and Network Advantage software.
