I have a recently purchased, unused switch.  I cannot access the administration page at ip 192.168.0.1.  It always gives a page not found error.  the ping is also unresponsive.  I have everything configured accordingly. 
 (client pc)

ip: 192.168.0.101/255.255.255.0;  

web browser: 192.168.0.1;  

error, page not found.

They turn them on, the "Systems" led is always flashing.  the power is fixed and the link blinks with use.

 I only connect the switch and a laptop, but if I connect to the router, the network connectivity is generated, but the problem is that I cannot access to manage the switch.  

help!!
