C9300-24P-E Description

The C9300-24P-E is a Cisco Catalyst 9300 Series stackable access switch for campus wiring closets that power PoE+ endpoints such as phones and access points. The switch has 24 10/100/1000 PoE+ ports on a 445W default PoE budget, a modular uplink slot, 208 Gbps of switching capacity and the Network Essentials license. That tier supports OSPF up to 1,000 routes but not BGP, VXLAN or MPLS.

Key Features

Shared 445W PoE+ Budget

All 24 PoE+ ports draw from 445W on the 715W supply, about 18.5W per port at full use. A second supply raises the budget to 720W, enough for 30W on every port.

Network Essentials Scope

The tier provides Layer 2 and routed access with OSPF up to 1,000 routes and MACsec-128. BGP, IS-IS, VXLAN and MPLS need the Advantage tier.

Uplink Speed Set By The Module

The uplink slot ships empty and takes Catalyst 9300 network modules, so uplink speed depends on the module installed rather than on the switch.

Application Scenarios

Office Floor Phones And Wi-Fi

On an office floor, the switch powers IP phones and Wi-Fi access points from its PoE+ ports and carries their traffic to the distribution layer through the uplink module.

Branch Office Access Stack

A branch office that outgrows a single switch can add members to a StackWise-480 stack, which links up to eight units at 480 Gbps.

Camera And Badge Reader Closet

In a school or warehouse wiring closet, the switch powers IP cameras and badge readers from PoE+ ports within its 445W default budget.

C9300-24P-E is the copper PoE+ model of this group: its 24 RJ-45 ports share 445W on the 715W supply, while C9300-24S-E puts 24 1G SFP fiber ports on the same supply with no PoE. Powered devices that draw up to 60W need C9300-24U-E, which supplies UPOE from an 830W budget on an 1100W supply and sits 1.5 in deeper. Sites that need BGP, IS-IS, VXLAN, MPLS or MACsec-256 at turn-up should order C9300-24P-A, or upgrade this switch later with a C9300-LIC= term (C9300-24-E-A-3, -5 or -7), which cannot be placed on the switch order. A stack accepts new members only at its current license level.

Ordering Checklist

  • Subscription tier and term: Select a 24-port Essentials term of 3, 5 or 7 years, such as C9300-DNA-E-24-5Y for Cisco DNA or C9300-DNX-E-24-5Y for Cisco Catalyst. New orders need a subscription of the same tier as the built-in Network Essentials license.
  • Smart Account: Name the Smart Account and virtual account that will hold the licenses. A Smart Account is mandatory on every Catalyst 9300 order.
  • Uplink module: The configurator adds C9300-NM-8X by default; keep it, pick another Catalyst 9300 module, or select C9300-NM-NONE. The uplink slot must hold a module or a blank.
  • Second power supply: A second PWR-C1-715WAC-P is added by default; C9300-SPS-NONE removes it. Without it the PoE budget stays at 445W instead of 720W.
  • Stack cables: A 50 cm StackWise cable and a 30 cm StackPower cable are added by default; C9300-STACK-NONE and C9300-SPWR-NONE remove them. A standalone switch otherwise receives cables it never uses.
  • Power cords: Select the cord type for the destination country; two cords ship with the default configuration. The configurator defaults to North America cords.

Questions & Answers

  • Can C9300-24P-E be stacked?

    Yes. C9300-24P-E stacks over StackWise-480 at 480 Gbps with up to 8 members. Members must be modular-uplink Catalyst 9300 switches at the same license level, and a 50 cm StackWise cable is added by default.
  • What does Network Essentials on C9300-24P-E include?

    Network Essentials on C9300-24P-E provides Layer 2 and routed access with OSPF up to 1,000 routes, plus MACsec-128. BGP, IS-IS, VXLAN and MPLS are not included. The license is perpetual and included with the hardware, and new orders need a subscription of the same tier.
  • How much power does C9300-24P-E draw with no PoE load?

    With a PWR-C1-715WAC-P supply, a C9300-NM-8X module and 115 VAC input, C9300-24P-E draws 107.1W at full port traffic and 100.7W at half port traffic. The weighted average is 99W, and the switch draws 85.8W with no link. These are the measured figures in the Catalyst 9300 data sheet.
  • Do PoE+ endpoints on C9300-24P-E stay powered during a reload?

    Perpetual PoE keeps endpoints powered through a soft reload, such as an upgrade, a crash or a manual reboot, and across a stack. It does not cover a power loss or hibernation. Fast PoE restores power in under 30 s from stored power and needs perpetual-poe-ha configured on the port.
  • Does a Network Essentials subscription for C9300-24P-E include ThousandEyes?

    No. ThousandEyes Network and Application Synthetics (TE-EMBEDDED-T) is bundled only with 3, 5 or 7-year Cisco Catalyst or Cisco DNA Advantage subscriptions on Catalyst 9300 switches, not with Essentials. A C9300-24P-E buyer who wants it needs the Advantage tier, so decide this when the license is quoted.
  • How much power does a PoE+ device receive from a port on C9300-24P-E?

    A PoE+ port on C9300-24P-E follows IEEE 802.3at Type 2 and sources 30W, so a powered device receives up to 25.5W after cable loss. An 802.3af Type 1 device receives 13W from a 15.4W source. Check endpoint specifications against the device figure, not the port rating.
  • What is the default packet buffer and NetFlow capacity of C9300-24P-E?

    C9300-24P-E has a 16-MB packet buffer and 64,000 Flexible NetFlow flows. The same Catalyst 9300 group lists 8 GB of DRAM and 16 GB of flash. Network Essentials limits routed scale separately, because OSPF stops at 1000 routes regardless of the hardware table size.
  • How are the 24 PoE+ ports of C9300-24P-E connected to the ASIC?

    C9300-24P-E uses one two-core UADP 2.0 ASIC with 8MB of buffer per core, and its 1G PHY groups cover 8 ports each. The uplink module connects over 10Gx4 or 40Gx1 lanes per cage, and StackWise-480 hangs off the same ASIC.
