Q1: I failed to log into the eWeb management system. What can I do?
Perform the following steps:
(1) Check that the network cable is properly connected to the LAN port of the device and the corresponding LED indicator
blinks or is steady on.
(2) Before accessing the configuration GUI, set the IP assignment mode to Obtain an IP address automatically
(recommended), so that the server with DHCP enabled can automatically assign an IP address to the PC. To designate a
static IP address to the PC, set the IP address of the PC in the same network segment as the IP address of the management
interface. For example, if the default IP address of the management interface is 192.168.110.1 and the subnet mask is
255.255.255.0, set the IP address of the PC to 192.168.110.X (X is any integer ranging from 2 to 254), and the subnet mask
is 255.255.255.0.
(3) Run the ping command to test the connectivity between the PC and the device.
(4) If the login failure persists, restore the device to factory settings.
Q2: What can I do if I forget my username and password? How to restore the factory settings?
To restore the factory settings, power on the device, and press and hold the Reset button for 5s or more, and release the
Reset button after the system LED indicator blinks. The device automatically restores the factory settings and restarts. The
original configuration will be lost after the factory settings are restored. After the restoration, the default management address
is 192.168.110.1 and the default password is admin.
Q3: The subnet mask value needs to be specified to divide the address range for certain functions. What are the
common subnet mask values?
A subnet mask is a 32-bit binary address that is used to differentiate between the network address and host address. The
subnet and the quantity of hosts in the subnet vary with the subnet mask.
Common subnet mask values include 8 (default subnet mask 255.0.0.0 for class A networks), 16 (default subnet mask
255.255.0.0 for class B networks), 24 (default subnet mask 255.255.255.0 for class C networks), and 32 (default subnet
mask 255.255.255.255 for a single IP address).
