43.2 Switch Access and Login
I can see the
Login
screen, but I cannot log in to the Switch. (I forgot the user name and/or
password.)
1
Check the Switch’s management mode by using the
CLOUD
LED.
•
If you are in Cloud management mode, use the
Local credentials Password
to log in to the cloud
mode – local GUI. The
Local credentials Password
can be found in
Site-wide
>
Configure
>
General
settings
>
Device configuration
:
Local credentials
:
Password
in the NCC portal.
•
If you are in standalone management mode, use the default user name
admin
and the default
password
1234
.
2
Depending on your Switch’s management mode, make sure you have entered the correct user name
and password. These fields are case-sensitive, please make sure [Caps Lock] is not on.
3
If this does not work, or you are not sure what the Switch’s management mode is, you have to reset the
device to its factory defaults (standalone management mode) first. See
for more
information on resetting the Switch. (Temporarily disconnect the Internet connection to the Switch after
the reset process, to prevent the Switch from being managed by NCC again.)
Note: After performing step
and you want to use the Cloud management mode, make sure
the Switch is registered in your organization and site in the NCC portal. To register the
Switch again, scan the QR code using the Zyxel Nebula Mobile app. See the
for more information on using the app to register the Switch.
I forgot the IP address for the Switch.
1
The default IP address is
http://DHCP-assigned IP
(when connecting to a DHCP server) or
192.168.1.1
.
2
Use the NCC (Nebula Control Center) or the ZON utility to find the IP address. The Switch must be
registered and added to a site in Nebula in order for it to be managed using Nebula.
Note: When your PC is directly connected to the Switch, you can always use the domain
name “setup.zyxel” to access the Web Configurator. This requires your PC to be able to
connect to a DNS server via the Switch.
3
If the Switch is removed from a site in Nebula, all the settings in the configuration file are reset to the
Nebula factory defaults except for the IP address. If you changed the default dynamic IP address to a
static IP address while the Switch was in a site in Nebula, the Switch will retain that static IP address after
you remove it from the site in Nebula.
4
If this does not work, you have to reset the device to its factory defaults. See
.
I cannot see or access the
Login
screen in the Web Configurator.
