Meraki MS355-24X-HW MS355 Switch – 16x 1G + 8x 10G mGig, 4x 10G SFP+

About the MS355-24X-HW

Two kinds of copper port share the MS355-24X-HW: 16 at 10/100/1000 and eight multigigabit ports at 100M, 1G, 2.5G, 5G or 10G. On top of that it has four 10G SFP+ and two 40G QSFP+ uplinks, a 740 W UPOE budget and 352 Gbps of switching capacity in 1U.

One 1025 W AC power supply, the MA-PWR-1025WAC, is included, and the second hot-swappable bay takes another for two power supplies. Idle draw is 110 W and maximum draw is 1793 W. Managed from the Meraki Dashboard.

Two dedicated stack ports give 400 Gbps of stacking bandwidth over the stacking cables listed under Sold separately. The C9300X-24HX-M is the newer model in this line.

What’s included

• MS355-24X-HW switch with 16 gigabit ports, eight multigigabit ports, four 10G SFP+ and two 40G QSFP+ uplinks
• One MA-PWR-1025WAC power supply

Sold separately

• A second MA-PWR-1025WAC power supply for redundancy
