Arista CCS-750X-48THP-LC | 750X 48-Port Gigabit PoE+ Line Card, 90W per Port

Q: Which Arista chassis models support the CCS-750X-48THP-LC line card?
A: This line card is compatible with the Arista 750X Series modular switches, specifically the CCS-755 (5-slot) and CCS-758 (8-slot) chassis. Each line card provides 48 ports, and the 8-slot chassis can support up to 384 ports when fully populated.

Q: What is the maximum PoE power this line card can deliver?
A: The CCS-750X-48THP-LC supports 802.3bt PoE+ with up to 90W per port. The total PoE budget depends on the number and capacity of power supplies installed in the chassis. Cognitive power management dynamically allocates power based on device requirements and priority settings.

Q: Does this line card support Layer 3 routing features?
A: Yes, the 750X Series line cards support both Layer 2 and Layer 3 forwarding. Routing features include OSPF, BGP, and VRRP, with all packet processing handled by the centralized switch cards. The line card also supports VXLAN and EVPN for campus segmentation.

Q: Is MACsec encryption available on this module?
A: Yes, all 48 ports support 256-bit MACsec encryption for dataplane security. MACsec is a separately licensed feature at the system level and provides zero-trust security for communications between endpoints and the network core.

Q: Can I mix this line card with other 750X Series modules?
A: Yes, the 750X Series supports mixing and matching line cards with different speeds and PoE capabilities, including 1G, 2.5G, 5G, and 10G modules. This provides flexibility for pay-as-you-grow deployments and future-proofing campus networks.
