C9300-48P-E Description

The C9300-48P-E is a Cisco Catalyst 9300 Series stackable access switch for wiring closets that power IP phones, access points and cameras over PoE+. The switch has 48 10/100/1000 PoE+ ports with a 437W default PoE budget, a modular uplink slot and 256 Gbps of switching capacity, with Network Essentials built in. The -E suffix covers Layer 2 and OSPF routing up to 1,000 routes but not VXLAN, Cisco TrustSec or MACsec-256.

Key Features

PoE+ Budget On The Default Supply

The default 715W supply leaves 437W for PoE, about 9W per port if all 48 ports draw power at once. Phones and access points fit comfortably; a full 30W on every port does not.

Second Supply Raises PoE To 1440W

A second 1100W or 1900W supply raises the budget to 1440W, which covers 30W on all 48 ports. A primary 1100W supply alone gives 822W to 1440W.

Modular Uplink Slot

The slot takes hot-swappable network modules: C9300-NM-8X (eight 10G/1G SFP+), C9300-NM-2Q (two 40G QSFP+), C9300-NM-2Y (two 25G SFP28), C9300-NM-4M (four Multigigabit) or C9300-NM-4G (four 1G SFP). Uplink speed changes by swapping the module, not the switch.

StackWise-480 With StackPower

Up to eight switches stack at 480 Gbps over StackWise cables, and only with other C9300 modular-uplink models on the same license tier. StackPower pools power across up to four members, or eight with XPS-2200.

Network Essentials Scope

Essentials covers Layer 2, routed access with OSPF up to 1,000 routes, PVLAN, VRRP, 802.1X and MACsec-128. BGP, VXLAN, MPLS and MACsec-256 sit outside the tier.

Rear USB 3.0 SSD Bay

A rear bay takes a 120 GB or 240 GB USB 3.0 SSD module for local storage and packet capture, so closet troubleshooting does not need a separate capture appliance.

Application Scenarios

Office Floor Wiring Closet

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 over the uplink module.

School Building Access

A school building can route between classroom VLANs at the access layer with OSPF and authenticate student and staff devices with 802.1X.

Camera Aggregation Closet

A closet that collects PoE+ security cameras from a warehouse or parking structure can power them from the switch and send the video streams upstream over a fiber uplink module.

C9300-48P-E is the PoE+ model of this group: its 48 copper ports share a 437W budget on the default 715W supply, while C9300-48T-E has the same chassis and modular uplink on a 350W supply with no PoE, which suits closets without powered devices. Closets with endpoints above the 30W PoE+ class need C9300-48H-E, which supplies Cisco UPOE+ with an 822W default budget on an 1100W supply. Network Essentials covers Layer 2 and OSPF up to 1,000 routes; when VXLAN, Cisco TrustSec or MACsec-256 is needed on day one, order C9300-48P-A, or upgrade an installed switch later with a C9300-LIC= term (C9300-48-E-A-3, -5 or -7), which cannot be placed on the switch order.

Ordering Checklist

  • Subscription tier: Order a 48-port Essentials term: C9300-DNA-E-48 (Cisco DNA) or C9300-DNX-E-48-3Y/5Y/7Y (Cisco Catalyst). The configurator defaults to Advantage, which does not match a Network Essentials switch on a new order.
  • Uplink module: Keep the default C9300-NM-8X, change it to another C9300-NM module, or select C9300-NM-NONE. The uplink slot must hold a module or be ordered empty, and the module is part of the switch order.
  • Second power supply: A second PWR-C1-715WAC-P is selected by default and C9300-SPS-NONE removes it. The second supply stays on the order unless removed, and a single-supply closet runs on the primary supply’s PoE budget.
  • Stacking cables: The default 50 cm StackWise cable (C9300-STACK-NONE removes it) and default 30 cm StackPower cable (C9300-SPWR-NONE removes it) are both added by default. A standalone switch uses neither.
  • Power cords: Select the cord type for the destination country; two cords ship with the order. The configurator defaults to North America cords.

Questions & Answers

  • Can C9300-48P-E be stacked?

    Yes. C9300-48P-E stacks up to 8 members over StackWise-480 at 480 Gbps per stack. Members must be other C9300 modular-uplink models on the same license tier, and StackPower pools power across up to four members, or eight with XPS-2200.
  • What does Network Essentials on C9300-48P-E include?

    Network Essentials on C9300-48P-E includes Layer 2 switching, OSPF routed access up to 1,000 routes, PVLAN, VRRP, 802.1X and MACsec-128. MACsec-256, Cisco TrustSec and VXLAN fall outside the tier, so the -E suffix suits routed access closets.
  • What PoE power level does C9300-48P-E source per port, and what reaches the device?

    Each PoE+ port sources 30W under IEEE 802.3at Type 2, and the powered device receives 25.5W. Type 3 and Type 4 802.3bt devices need a UPOE or UPOE+ model, so keep C9300-48P-E for phones, access points and cameras that fit the 802.3at class.
  • Must an empty uplink slot on C9300-48P-E hold a blank module?

    Yes. An empty network module slot needs a C9300-NM-BLANK installed to maintain proper airflow. If the order skips the uplink module, add the blank, and put it back whenever a module is pulled for service on C9300-48P-E.
  • What are the PWR-C1-1100WAC-P heat output and input range when fitted to C9300-48P-E?

    PWR-C1-1100WAC-P is rated 1100W with roughly 3754-3793 BTU/hr of output. It takes 115-240VAC at 47-63Hz through an IEC 320-C16 inlet. Fitting it as the primary supply raises the available PoE budget on C9300-48P-E to 822W-1440W, per the Catalyst 9300 data sheet.
  • Does PWR-C1-1900WAC-P reach its full output on 115V in C9300-48P-E?

    No. PWR-C1-1900WAC-P outputs up to 1900W on 230V input and is limited to 1500W on 115V input. Heat output is 6483 BTU/hr at 230V, so a 115V closet circuit caps the usable power for the PoE budget. The supply also needs its own power cord, so check the cord on the quote.
  • Is ThousandEyes bundled with an Essentials subscription for C9300-48P-E?

    No. TE-EMBEDDED-T, the ThousandEyes Network and Application Synthetics license, ships by default only with 3, 5 or 7-year Cisco Catalyst or Cisco DNA Advantage subscriptions. A Network Essentials subscription for C9300-48P-E does not include it, so an Advantage tier is needed to get it.
  • Does C9300-48P-E support BGP, VXLAN or MPLS with its Network Essentials license?

    No. BGP, VRF, VXLAN, LISP, TrustSec and MPLS come with Network Advantage, which adds them on top of Network Essentials. The same applies to the AVB, PTP and CoAP IoT protocols and to CLI software patching. Order the Network Advantage version of the switch when the closet needs any of these features.
  • How many VLAN IDs and routed ports does a stack with C9300-48P-E support?

    C9300-48P-E supports 4094 VLAN IDs and 1000 SVIs, and a stack supports up to 448 routed ports. It also holds 300 PVST instances and 13,000 STP virtual ports. These limits are the same on Network Essentials as on Network Advantage, so the license tier does not change how many VLANs or routed interfaces a design can use.
  • Which spare fan module PID fits C9300-48P-E?

    Yes. The three fan modules are field-replaceable and support N+1 redundancy. The spare fan module PID is FAN-T2= and its MTBF is 4,521,330 hours. A failed fan can be swapped in the closet without taking C9300-48P-E out of service.
