      • [NVR] HDD Replacement Guide for RAID Operations

      HIT :17

      ■ When using a RAID 5/6, mixing HDD with different manufacturers or different capacities is not recommended as a reliability issue.


      EX) If HDD capacity is different, it can be operated as below.

      - Lower capacity HDD replacement than failed HDD → RAID is not rebuilding.

      - Higher capacity HDD replacement than failed HDD → RAID can rebuild. However, it can be operated as much as the HDD capacity that was used before.


      ※ Precautions

      1) If the same model cannot be replaced due to HDD discontinuation, we recommend using the same manufacturer and the same capacity.

         For stable equipment operation, it is recommended to have the same HDD in stock in advance.

      2) If one HDD is replaced due to a failure while using RAID, automatic recovery mode is executed and a recovery action warning is issued.

      3) RAID Rebuilding is not possible if more than one HDD fails while using RAID. (RAID 5)

      • I received a warning message "Recording Bandwidth Exceeded."

      HIT :310

      Each NVR has a different recording bandwidth limit. Recording must take place within the bandwidth.
      It is necessary to modify the settings for the overall recording bandwidth and allowance.

      • What is PnP Mode?

      HIT :722

      Before PNP (Plug and Play) was introduced, many users had difficulties in registering and configuring cameras manually.

      It allows automatic registration and setup of NVR like that of existing DVR.

      For this, N/W camera must be at default setting, and NVR POE terminal must be connected 1:1.

      • What is Manual Mode?

      HIT :582

      You use Manual Mode when you register a camera manually rather than automatically (PNP).
      If the network used at the site where NVR is installed is a secured network or if the distance from the camera is too far
      You can select a mode at Menu - System Configuration - System Management - Setup Information.
