Description

The Catalyst 9300LM is the compact 'mini' variant of the Catalyst 9300 Series, built for enterprise campus and branch access layers where high-density UPOE is needed to power IP phones, wireless access points, cameras, IoT and smart building devices. It suits SD-Access fabric edge deployments and hybrid wired and wireless networks, managed on premises with Catalyst Center or migrated to Meraki cloud management.

This SKU provides 48 x 1G copper ports (1G/100M/10M) with Cisco UPOE at up to 60W per port, plus 4 x 25G fixed SFP28 uplinks to the distribution or core layer. The default 1000W AC power supply (PWR-C6-1KWAC) delivers 790W of available PoE power, and a second supply can be added for redundancy or a larger budget. Switching capacity is 296 Gbps, rising to 616 Gbps when stacked, with 220.22 Mpps forwarding.

The -A suffix denotes the perpetual Network Advantage licence, which adds advanced routing, segmentation and MACsec-256 to the base feature set. Stacking uses StackWise-320 with up to 8 members, joining only other Catalyst 9300L and 9300LM models at the same licence level.

FAQs

Q: Which licence does this switch ship with?
A: The -A suffix indicates the perpetual Network Advantage licence, which includes advanced routing (BGP, EIGRP, IS-IS, HSRP, OSPF), segmentation (VRF, VXLAN, LISP, TrustSec, MPLS) and MACsec-256. A Cisco Catalyst subscription term licence is also used through Smart Licensing.

Q: How much PoE power does it provide?
A: With the default 1000W AC power supply (PWR-C6-1KWAC) the switch has 790W of available PoE power. Adding a 600W AC secondary supply raises this to 1390W, a 715W DC secondary gives 1505W, and a second 1000W AC supply gives up to 1790W, limited by port count and rating.

Q: What can it be stacked with?
A: It stacks using StackWise-320 with up to 8 members, but only with other Catalyst 9300L and 9300LM models at the same licence level. It requires the C9300L-STACK-KIT2 and STACK-T3A stacking cables, and cannot be stacked with modular-uplink Catalyst 9300 or 9300X models.

Q: Which optics fit the 25G uplinks?
A: The 4 x 25G fixed uplinks accept SFP28, SFP+ and SFP optics. The uplinks are fixed, so Catalyst 9300 network modules are not supported.

Q: Does it use the same power supplies as other Catalyst 9300 models?
A: No. The C9300LM family uses different power supplies from the Catalyst 9300, 9300X and 9300L models. It uses the PWR-C6-1KWAC, PWR-C6-600WAC and PWR-C6-715WDC supplies.

Q: Which software version does it need?
A: It requires Cisco IOS XE 16.11.1b or later, which applies to the Catalyst 9300L series.
