FAQs

Q: What is multi-gigabit (mGig) support on this switch?
A: The MS355-48X2 features 24 multi-gigabit ports that auto-negotiate at 100M, 1G, 2.5G, 5G, or 10G speeds over standard copper cabling, making it ideal for supporting 802.11ax (Wi-Fi 6) access points and high-bandwidth workstations without requiring fiber.

Q: How much PoE power can each port deliver?
A: All 48 ports support PoE+/UPoE (802.3af/at/bt). The switch offers a 740W total PoE budget and can deliver up to 60W per port for UPoE-compatible devices such as high-performance wireless access points, PTZ cameras, and video conferencing endpoints.

Q: Can I stack multiple MS355-48X2 switches?
A: Yes, the MS355-48X2 includes two dedicated 100G QSFP28 hardware stacking ports providing 400 Gbps of stacking bandwidth. You can stack up to 8 units for simplified management and increased redundancy.

Q: Does this switch require a Meraki license to operate?
A: Yes, the MS355-48X2 requires a Meraki Enterprise license for full operation and cloud management. The license is sold separately and is required for the switch to pass traffic and be managed via the Meraki dashboard.

Q: What Layer 3 routing capabilities does the MS355-48X2 support?
A: The MS355-48X2 is a full Layer 3 switch supporting static routing, OSPF, VRRP for warm spare redundancy, inter-VLAN routing, DHCP server and relay, and IPv4/IPv6 ACLs for traffic filtering and segmentation.
