The default warranty is three months! Take the picture with 15 words of praise and extend the warranty for three months! no sooner said than done! Let''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s write a good review!
Can help to set up soft routing to expand WAN!
The clean room of the local company was removed from the shelf for recycling, 90% new, and the test is normal! No dismantling, no repair! Restore factory settings before shipment! Get the power cord when you buy it! No ears by default, please leave a message if you need ears!
The feature of this machine is silent! Mute! Mute!
stable! Three-tier switch! After such a big machine is turned on and enters the system, there is basically no sound!
The owner recommends dual power supplies(Double electric redundancy, even if one power supply is broken, the machine will not stop)
Dark gray: 48 Gigabit electrical ports single power supply +379 yuan
light grey:48 Gigabit electrical ports dual power supply 499 yuan
A 4-port Gigabit optical fiber module board is 80 yuan each!
Cisco Gigabit multimode fiber optic module 9.9 yuan a!

In summary! Cisco''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s 48-port Gigabit switch with dual power supplies will sell for 450 yuan! It''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s still three-tier, with management! When the brand new was first launched, it was a smaller one than 20,000! Only 450 now!
What is Cisco? The Cisco brand is like Apple in network products, the Apple in network equipment! Cisco dares to be the second in network equipment, no one dares to be the first! Fortune 500 companies Apple ranked ninth, Cisco ranked 15th!
The self-developed system is really good! 3560X is a new model, there is no stacking port, and it does not support stacking! It is a three-tier switch! The backplane bandwidth is 160G, and the packet forwarding rate is 101.2m, which is comparable to H3C and Huawei switches of the same level! And the workmanship is better than them, it is quieter and more stable! Especially Cisco''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s system software is optimized! Can better play the hardware performance! This is something that H3C and Huawei can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t compare! The net weight of the machine with dual power supplies is 8.78 kg! It can be seen its workmanship and quality! Some domestic switches dare to spend so much money! Without this workmanship, how could he dare to guarantee a mean time between failures of 171,846 hours!
Unexpectedly! A major feature of this Cisco''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s three-tier switch is mute! Actual measurement!
After the Cisco 3560X machine enters the system normally:
Power location: 17 decibels
Fan position: 37 decibels
Port position: 20 decibels
1 meter away from the fan position: 11 decibels
After the H3C S5120 machine enters the system normally:
Power location: 35 decibels
Fan position: 58 decibels
Port position: 54 decibels
1 meter away from the fan position: 17 decibels
Why is it muted?
Cisco chose NEC/Delta''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s dual ball bearing fan!
Fans are divided into three categories:
The first ball bearing!(Single ball, double ball! Double balls are better!)Quiet life is very long!(It can reach 150,000 hours)This is ours! Double motor 4 bearings!
The second hydraulic bearing! Long silent life!
The third oil bearing! It''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s an ordinary desktop fan! When the oil dries, the noise comes, and it doesn''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t turn!
Why is it stable?
The power supply is 350W plug-in power supply from Delta or Taiwan Lite-On!
They are all Taiwanese! Delta can be said to be the first brother of the power supply!
Not only did Cisco choose Delta power supplies, but HP also chose Delta for its server workstations! It can be seen that the quality of Delta, otherwise how would these big brothers choose!
And also supports dual power redundancy! The network equipment needs stability, once the power is cut off, the network is cut off! What a loss! Put on two power supplies, it is impossible for the two power supplies to be broken at the same time! That''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s too much back! All the broken ones will not affect the operation of the machine, so find out in time to replace them! Hot-swappable, the other power supply does not need to be powered off, directly on! A yellow light will report an error if the power supply is broken, which is easy to identify!
