Thecus 2TB Storage Server 200W Single PSU 1U4500S_4050 Leaflet

The 1U4500 supports external USB hard disks through its three USB ports. Once 
a USB hard disk has successfully mounted, the entire volume will be copied 

automatically to the default USB HDD folder. The 1U4500 supports up to 6 USB 
external storage devices. All file names on the USB disk volume are case sensitive. 

 
The 1U4500 also supports eSATA hard disks with its eSATA port. 

 
Before attaching an eSATA or USB disk drive to 1U4500, you have to partition 

and format it on a desktop computer or a notebook first. The attached device will 
be located at \\192.168.1.100\usbhdd\sdf1 where 192.168.1.100 means the 
IP address of 1U4500 and sdf1 stands for the first partition on disk #6, the 
eSATA or USB disk drive. If it is an NTFS partition, NAS users can open or copy 
files from \\192.168.1.100\usbhdd\sdf1 but cannot add new files or modify 
existing files.  
 

If you want to write to an USB storage device, the file system must be 
FAT32.

With a RAID 1, RAID 5, RAID 6, or RAID 10 volume, you can add a spare disk 
after the initial RAID is setup. To add a spare disk, follow the steps below: 

 

1.  On the RAID Configuration Screen, tick the checkbox of the hard disk 

you wish to designate as a spare disk. 

 

2.  Click Add Spare. The disk will be configured as a spare disk. The system 

automatically rebuilds the spare disk when one of the disks in the RAID set 
fails.  

 

1U4500 can operate in dual mode. When connecting to a regular USB disk or 
thumb drive, 1U4500 is acting as USB host. When connecting to a PC thru its USB 

Type B connector on the back panel, 1U4500 can act as a USB disk. This feature 
allows user to transfer files without using network connection. 

 
When you create RAID, you can assign a portion of space on the RAID to be used 

as USB disk. When connecting 1U4500 to a PC using the supplied USB A to B 
cable, the PC will recognize this space as an unformatted disk. At this point, the 

PC can format this portion of disk and create file system on it. Since this disk is 
created on the RAID, it will be protected by the RAID level you select. 
 

 

When RAID is removed or damaged, all the data on the Target USB 
device will be deleted.
