FAQs

Q: What is the difference between the WS-C3850-48XS-E and WS-C3850-48XS-S models?
A: The main difference is the software feature set. The WS-C3850-48XS-E includes the IP Services license, which provides advanced Layer 3 routing capabilities including OSPF, EIGRP, BGP, and policy-based routing. The WS-C3850-48XS-S includes the IP Base license with standard Layer 3 routing features.

Q: Is the WS-C3850-48XS-E stackable with other Catalyst 3850 models?
A: No, the 48XS models are unique in the Catalyst 3850 series in that they do not support StackWise-480 stacking capability. These models are designed as standalone switches with fixed 40G QSFP+ uplinks instead of modular network modules.

Q: Can I use 1G SFP modules in the SFP+ ports?
A: Yes, the SFP+ ports are backwards compatible with 1G SFP modules, allowing you to mix 1G and 10G connectivity based on your requirements. This provides flexibility for gradual network upgrades.

Q: Does this switch support Power over Ethernet (PoE)?
A: No, the WS-C3850-48XS-E is a non-PoE model designed for fiber-based connectivity. The SFP+ ports are for optical transceivers and direct attach cables (DAC) only and do not support PoE delivery.

Q: What redundancy options are available for this switch?
A: The switch supports dual redundant hot-swappable power supplies for 1+1 power redundancy. It also includes three field-replaceable fan modules. However, it does not support StackWise-480 or StackPower features.
