Does C9300-48P-A support BGP?

Yes. Network Advantage on C9300-48P-A adds BGP and unrestricted OSPF, along with VRF, VXLAN, LISP, Cisco TrustSec, MPLS and MACsec-256. NETCONF, RESTCONF and Open PnP automation come with it. New orders need a subscription of the same tier, C9300-DNA-A-48-3Y, -5Y or -7Y.

What power does a device receive from a PoE+ port on C9300-48P-A?

A PoE+ port follows IEEE 802.3at Type 2, so the switch sources 30W and the powered device receives 25.5W. A device whose class needs more than 25.5W is not served at full power, so match the endpoint class to the port before ordering.

Do I need a C9300-NM-BLANK in an empty uplink slot of C9300-48P-A?

Yes. A network module slot with no module installed must hold a C9300-NM-BLANK to maintain proper airflow. Add the blank to the order when C9300-48P-A ships without an uplink module, and keep it in place whenever you remove a module for service.

How much heat does the default PWR-C1-715WAC-P of C9300-48P-A produce?

PWR-C1-715WAC-P is rated 715W with an output of 2440 BTU/hr. It takes 100-240VAC at 47-63Hz through an IEC 320-C16 inlet. Size closet cooling for the combined heat of both supplies when a second supply is fitted, and order power cords that match the inlet type and the closet outlet.

What does PWR-C1-1900WAC-P output on 115V input in C9300-48P-A?

PWR-C1-1900WAC-P is a Platinum-class supply. It outputs up to 1900W on 230V input and is limited to 1500W on 115V input. Heat output is 5118 BTU/hr at 115V, so the closet circuit decides the usable power and the heat load.

What storage and humidity limits apply to C9300-48P-A before installation?

Storage temperature for C9300-48P-A is -40C to +70C, and storage altitude is up to 15,000 ft (4500m). Operating and non-operating relative humidity is 5%-90% non-condensing. Operation is limited to altitudes up to 10,000 ft, so check these limits before the switch sits in a warehouse or an unconditioned closet.

How many VLANs, SVIs and routed ports does C9300-48P-A support?

C9300-48P-A supports 4094 VLAN IDs, 1000 SVIs and 300 PVST instances. A stack of C9300-48P-A switches supports up to 448 routed ports and 13,000 STP virtual ports. Jumbo frames are supported up to 9198 bytes, so size the layer 3 design against these limits.

Does a Network Advantage subscription for C9300-48P-A include ThousandEyes and Cisco Spaces Extend?

Yes. TE-EMBEDDED-T (ThousandEyes Network and Application Synthetics) and D-DNAS-EXT-S-T (Cisco Spaces Extend) are bundled by default with 3, 5 or 7-year Cisco Catalyst or Cisco DNA Advantage subscriptions. Essentials subscriptions do not carry the ThousandEyes license.

Which IoT protocols and patching features does Network Advantage add on C9300-48P-A?

Network Advantage adds AVB, PTP and CoAP IoT protocols, plus CLI software patching, NSF, GIR and xFSU high availability. Network Essentials does not carry them, so choose the -A suffix when PoE+ cameras, building controllers or audio-video endpoints need time sync or in-service patching.

Do PoE+ devices on C9300-48P-A keep power during a software reload?

Yes for soft reloads. Perpetual PoE keeps device power through an upgrade, a crash or a manual reboot, and it works across a stack. It does not cover power loss, front-end processor removal or hibernation. Fast PoE restores device power in under 30 seconds and needs perpetual-poe-ha on the port.

C9300-48P-A Description

The C9300-48P-A 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 Advantage built in. A full 30W on all 48 ports needs the 1440W maximum budget, which requires a second 1100W or 1900W supply.

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 Advantage Feature Set

Advantage adds BGP, unrestricted OSPF, VRF, VXLAN, LISP, Cisco TrustSec, MPLS and MACsec-256, plus NETCONF, RESTCONF and Open PnP automation.

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.

Hospital And Campus Buildings

A hospital or campus building that segments clinical, guest and building-systems traffic can use the VRF, VXLAN and Cisco TrustSec features of Network Advantage at the access edge.

Branch Stack With 10G Uplinks

A branch office can stack several of these switches over StackWise-480 and run one 10G uplink module to the site core, managing the whole stack as a single switch.

C9300-48P-A is the PoE+ model of this group: its 48 copper ports share a 437W budget on the default 715W supply, while C9300-48T-A 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-A, which supplies Cisco UPOE+ with an 822W default budget on an 1100W supply. C9300-48P-A carries Network Advantage; a site that needs only Layer 2 and OSPF up to 1,000 routes can order C9300-48P-E instead, though there is no downgrade path from Advantage once the switch is bought.

PoE Power Planning

Planning Item	Value or Check
Default PoE budget	437W with the default PWR-C1-715WAC-P supply
Extended PoE budget	Up to 1440W with a second 1100W or 1900W supply installed, subject to port-count limits
PoE standard supported	Cisco PoE+ (IEEE 802.3at class)
Power supply slots	2 internal slots; unused slot needs a blank module for airflow
Device count check	Confirm total connected PD wattage against the 437W default budget before adding endpoints
Stacking power note	StackPower can share power across stack members but does not replace confirming per-unit PoE budget

Ordering Checklist

Subscription tier: Order a 48-port Advantage term: C9300-DNA-A-48-3Y/5Y/7Y (Cisco DNA) or the C9300-DNX-A-48 Cisco Catalyst equivalent. New orders need a subscription of the same tier as the built-in Network Advantage license; the configurator defaults to a 5-year Cisco DNA Advantage term.
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-A be stacked?
Yes. C9300-48P-A stacks over StackWise-480 with up to eight members, 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.
Does C9300-48P-A support BGP?
Yes. Network Advantage on C9300-48P-A adds BGP and unrestricted OSPF, along with VRF, VXLAN, LISP, Cisco TrustSec, MPLS and MACsec-256. NETCONF, RESTCONF and Open PnP automation come with it. New orders need a subscription of the same tier, C9300-DNA-A-48-3Y, -5Y or -7Y.
What power does a device receive from a PoE+ port on C9300-48P-A?
A PoE+ port follows IEEE 802.3at Type 2, so the switch sources 30W and the powered device receives 25.5W. A device whose class needs more than 25.5W is not served at full power, so match the endpoint class to the port before ordering.
Do I need a C9300-NM-BLANK in an empty uplink slot of C9300-48P-A?
Yes. A network module slot with no module installed must hold a C9300-NM-BLANK to maintain proper airflow. Add the blank to the order when C9300-48P-A ships without an uplink module, and keep it in place whenever you remove a module for service.
How much heat does the default PWR-C1-715WAC-P of C9300-48P-A produce?
PWR-C1-715WAC-P is rated 715W with an output of 2440 BTU/hr. It takes 100-240VAC at 47-63Hz through an IEC 320-C16 inlet. Size closet cooling for the combined heat of both supplies when a second supply is fitted, and order power cords that match the inlet type and the closet outlet.
What does PWR-C1-1900WAC-P output on 115V input in C9300-48P-A?
PWR-C1-1900WAC-P is a Platinum-class supply. It outputs up to 1900W on 230V input and is limited to 1500W on 115V input. Heat output is 5118 BTU/hr at 115V, so the closet circuit decides the usable power and the heat load.
What storage and humidity limits apply to C9300-48P-A before installation?
Storage temperature for C9300-48P-A is -40C to +70C, and storage altitude is up to 15,000 ft (4500m). Operating and non-operating relative humidity is 5%-90% non-condensing. Operation is limited to altitudes up to 10,000 ft, so check these limits before the switch sits in a warehouse or an unconditioned closet.
How many VLANs, SVIs and routed ports does C9300-48P-A support?
C9300-48P-A supports 4094 VLAN IDs, 1000 SVIs and 300 PVST instances. A stack of C9300-48P-A switches supports up to 448 routed ports and 13,000 STP virtual ports. Jumbo frames are supported up to 9198 bytes, so size the layer 3 design against these limits.
Does a Network Advantage subscription for C9300-48P-A include ThousandEyes and Cisco Spaces Extend?
Yes. TE-EMBEDDED-T (ThousandEyes Network and Application Synthetics) and D-DNAS-EXT-S-T (Cisco Spaces Extend) are bundled by default with 3, 5 or 7-year Cisco Catalyst or Cisco DNA Advantage subscriptions. Essentials subscriptions do not carry the ThousandEyes license.
Which IoT protocols and patching features does Network Advantage add on C9300-48P-A?
Network Advantage adds AVB, PTP and CoAP IoT protocols, plus CLI software patching, NSF, GIR and xFSU high availability. Network Essentials does not carry them, so choose the -A suffix when PoE+ cameras, building controllers or audio-video endpoints need time sync or in-service patching.
Do PoE+ devices on C9300-48P-A keep power during a software reload?
Yes for soft reloads. Perpetual PoE keeps device power through an upgrade, a crash or a manual reboot, and it works across a stack. It does not cover power loss, front-end processor removal or hibernation. Fast PoE restores device power in under 30 seconds and needs perpetual-poe-ha on the port.
