Why I cannot make a backup on ZyXEL Communications Storage?
If you cannot make a backup on your ZyXEL Communications Storage, check that enough space is available on the external disk. Also, verify that the NAS is not currently performing another backup job.
Why is the COPY LED red on my ZyXEL Communications NAS542?
If the COPY LED is red on your ZyXEL Communications Storage, the USB device or SD card may not be compatible with the NAS.
What does it mean if an HDD LED is off on ZyXEL Communications NAS542?
If an HDD LED is off on your ZyXEL Communications Storage, it means the NAS cannot detect a hard drive in the drive bay. You should replace or install a hard drive.
Why replacing smaller disks in a RAID 1, RAID 5, or RAID 6 with larger capacity hard disks did not expand the storage capacity of ZyXEL Communications Storage?
If replacing smaller disks with larger ones did not expand the storage capacity of your ZyXEL Communications Storage, it could be because the NAS rebooted during the RAID re-build. After the re-build finishes, go to the Storage Manager screens, select the volume or disk group, click 'Manage', and use 'Expand the volume with unallocated disk space'.
Why migrating from RAID 1 to RAID 5 did not expand the storage capacity on ZyXEL Communications NAS542?
If migrating from RAID 1 to RAID 5 did not expand the storage capacity on your ZyXEL Communications Storage, it may be because the NAS rebooted during the RAID re-build. After the re-build finishes, go to the Storage Manager screens, select the volume or disk group, click 'Manage', and use the 'Expand the volume with unallocated disk space' option.
What should I do if I forgot the password for ZyXEL Communications Storage?
The default password for ZyXEL Communications Storage is 1234. If you have changed it and forgotten it, you will have to reset the NAS.
What does it mean if an HDD LED is red on ZyXEL Communications Storage?
If an HDD LED is red on your ZyXEL Communications Storage, it indicates that the NAS has detected an error on the hard drive. It is recommended to replace the hard drive as errors suggest it may fail soon.
What to do if a local user cannot access a share on ZyXEL Communications NAS542 Storage?
If a local user cannot access a share on your ZyXEL Communications Storage, first ensure that the NAS is turned on and connected to the network. The local user should also verify that they have entered their login name and password correctly.
Why is the LAN LED off on my ZyXEL Communications NAS542?
The LAN LED may be off because the Ethernet cable is not properly connected to the ZyXEL Communications Storage and another Ethernet device, or the other device is not turned on. Ensure the Ethernet cable is correctly connected and the other device is powered on. If the issue persists, try using a different Ethernet cable.
