Product/Model Name: QNAP / TS-419P+ CPU: Marvell 6282 1.6GHz The firmware has been updated to the latest version (QTS 4.3.3.2784). The LAN ports x 2, USB ports x 4, and front LCD display are all working without issues. However, the eSATA port has not been tested as I do not have a compatible device. The unit has been cleaned with alcohol to some extent, but the original box has some dirt and scratches. The condition is relatively good, but as this is a used item, please refrain from purchasing if you are looking for a perfect appearance. I have tested the unit with four HDDs installed, configured in RAID 5, and confirmed file sharing via SMB. I am including one 500GB HDD for testing purposes, and have performed a basic initial setup. The HDD is currently showing as healthy, but it is for testing purposes only, and I cannot guarantee the HDD's operation. Please understand this. Since it has been initially set up, you can use and reconfigure it immediately from a PC with Qfinder installed. The initial settings are: ID: admin PW: admin You can use it as is, but please reconfigure it yourself, including volume expansion and RAID settings. You can use myQNAPcloud (remote access from smartphones, etc.) by registering a new account. ※Included Items※ ・Main unit ・Original box ・1 x 500GB HDD for testing (installed) ・Genuine AC adapter + power cable + 3-pin to 2-pin adapter ・16 x 3.5-inch HDD mounting screws (used) (4 installed) ・CD-R (manual, Qfinder, and various software) ※The firmware is also required for new settings, so it is also written on the CD-R (also available for download from the QNAP official website). If you do not need the HDD, it can be removed for a discount of ¥400. Please contact me via comment before purchasing. If there is a malfunction after arrival, returns are accepted within 3 days of arrival.
