48-Port Layer 3 Switch

The Brocade FastIron FCX648S is a managed Layer 3 switch built for enterprise campus networks. It provides 48 RJ45 ports at 10/100/1000 Mbps and four SFP uplinks in a 1U rackmount form factor. The 32K MAC address table supports dense endpoint connectivity.

Sustained Load Behaviour

Switching bandwidth reaches 200 Gbps full duplex with a forwarding rate of 150 Mpps under continuous traffic. Stacking bandwidth of 64 Gbps full duplex maintains performance across linked units. Dual 210 W redundant power supplies share load to keep the switch operating during extended demand.

Interface Practical Limits

RJ45 ports negotiate down to 10 Mbps and up to 1000 Mbps using 802.3ab, while SFP slots accept standard transceivers for fibre or copper uplinks. Jumbo frames up to 9000 bytes reduce overhead on large transfers. The 100-240 V AC input at 50-60 Hz suits global power environments.

Questions about this item

How much power do the dual 210 W AC supplies draw when the FCX648S runs continuously under full load?

Each internal supply is rated at 210 W and operates from 100-240 V AC at 50-60 Hz; the two units share the load and provide redundancy so the switch stays on if one fails.

What cabling and modules must I already have to use the 48 RJ45 ports and the four SFP uplinks on this switch?

The RJ45 ports accept standard Cat5e or better copper for 10/100/1000 Mbps links; the four SFP slots require compatible Brocade or third-party SFP transceivers and matching fibre or copper patch cords.

Will the FCX648S stack with older FastIron switches I already own, and what bandwidth does the stacking link provide?

Yes, it supports stacking with compatible FastIron models and delivers 64 Gbps of full-duplex stacking bandwidth across the dedicated stacking ports.
