Cisco Catalyst C9300-24S-E

Network Modules

Cisco Catalyst 9300 Series switches (C9300X and C9300 SKUs) support optional network modules for uplink ports. These modules offer flexibility for uplink speeds ranging from 1G to 40G, including multigigabit options for high-performance environments. The default switch configuration does not include the network module.

Power supplies

The Cisco Catalyst C9300-24S-E switch comes with a default AC power supply of 715W, specifically the PWR-C1-715WAC-P/2 model

Power Supply Details

• Default Power Supply: 715W AC (PWR-C1-715WAC-P/2)
• PoE Capability: Not applicable for this model (no PoE support)
• Stack Power Support: Yes — allows power sharing across a stack of switches
• Redundancy: Supports dual redundant power supplies for high availability

Stacking

Stacking the Cisco Catalyst C9300-24S-E switch is all about leveraging Cisco’s StackWise technology to create a unified, high-performance network fabric. You can stack up to eight switches using StackWise-480 cables, achieving up to 480 Gbps of stacking bandwidth. This setup simplifies management, boosts redundancy and high availability, if one switch fails, another seamlessly takes over, minimizing downtime. Simplified management all switches in the stack are managed as one, streamlining configuration and monitoring

Fan

Cisco Catalyst 9300 Series switches also come with three field-replaceable fans and support (N+1) redundancy.

Fan Module Details

• Hot-swappable: You can replace the fan module without powering down the switch.
• Redundant design: Typically includes multiple fans to ensure continued operation even if one fails.
• Smart cooling: The fans adjust speed based on internal temperature sensors to optimize airflow and reduce noise.

Installation & Maintenance

• The fan module is located on the rear panel of the switch.
• Cisco provides detailed instructions for installing and replacing the fan module in the
• It’s important to use Cisco-approved fan modules to maintain warranty and ensure compatibility
