Cloud Router Switch PoE CRS354-48P-4S+2Q+RM
Power all your devices while having the strongest performance – this 48 port PoE+ switch will rock any setup, including 40 Gbps devices!
If you are looking for a single switch that will put your network setup ahead of the curve and power
all the necessary devices – look no further! The new CRS354-48P-4S+2Q+RM is an effective and
adaptable rackmount solution for managing networks in the most demanding environments. Unlike
many other switches out there, our products are made with the system administrator in mind.
High-end performance with PoE-out for the masses: more 10G ports and even 40G ports, because speed matters
This powerful switch has 48 x 1G RJ45 ports and 4 x 10G SFP+ ports. There are also 2 x 40G QSFP+
ports for extremely fast fiber connections or linking with other 40 Gbps devices. All 48 Ethernet ports
offer different power output options: Passive PoE, low voltage PoE, 802.3af/at (Type 1 “PoE” / Type 2
“PoE+”) with auto-sensing, making this switch the easiest solution to power even the largest setups.
We have included a mighty power supply that can provide 750 W of power – this switch can handle
a lot. And there is a special bracket for easy cable management.
The 48 port champion you’ve been waiting for – this is the bargain of the decade! Now with PoE-out!
CRS354-48P-4S+2Q+RM is extremely functional, and it has the best price-point on the market – it will
make the perfect addition to a professional setup.
The total non-blocking throughput is 168 Gbps, switching capacity is 336 Gbps and the forwarding rate
reaches 235 Mpps
