4.1. Cabling Instructions

An example of connecting a QNAP NAS to four REXP-1200U-RP enclosures is shown below.

1	Connect the QNAP NAS to the REXP-1220U-RP:If one REXP-1200U-RP enclosure is configured, connect storage expansion ports on the NAS to the expansion port of the enclosure.
2	Connect the REXP-1220U-RP to other REXP-1220U-RP:If two REXP-1220U-RP enclosures are configured, connect one of *the mini SAS ports to a port on the other REXP-1220U-RP using the external Mini SAS cable (SFF-8644).(*Note: An optional storage expansion card is required on the QNAP NAS.)

An example of connecting a QNAP NAS to four REXP-1200U-RP enclosures is shown below.

1	Connect the QNAP NAS to the REXP-1200U-RP:If two (or above) REXP-1200U-RP enclosures are configured, connect the two storage expansion ports on the NAS to two REXP-1200U-RP enclosures for maximized performance.
2	Connect the QNAP NAS to the REXP-1200U-RP:Connect the storage expansion port* on the QNAP NAS to the IN (●●) port of a REXP-1200U-RP using the external Mini SAS cable (SFF-8088).(*Note: Optional storage expansion card is required on the QNAP NAS.)
3	Connect the REXP-1200U-RP to another REXP-1200U-RP:Connect a Mini SAS cable (SFF-8088) from the OUT (◆◆) port of the REXP-1200U-RP to the IN (●●) port of another REXP-1200U-RP.

Caution: Do not connect an OUT port (◆◆) to another OUT port (◆◆) or an IN port

(●●) to another IN port (●●).

An example of connecting a QNAP NAS to four REXP-1000 Pro enclosures is shown below.

1	Connect the QNAP NAS to the REXP-1000 Pro:If two (or above) REXP-1000 Pro enclosures are configured, connect the two storage expansion ports on the NAS to two REXP-1000 Pro enclosures for maximized performance.

4.2. Mini SAS Cable Removal

Follow the steps below to remove the Mini SAS cable:

1. Pull up the restraining clip latch of the Mini SAS cable.
2. Remove the Mini SAS cable from its restraining clip.

Chapter 5. Remove an Air Duct (Applied to REXP-1600U-RP)

Unlatch the air duct with your thumb and index finger. Pull the air duct upward to disengage it from the RAID expansion enclosure.

Chapter 6. Install/Remove a Fan Module

6.1. Install a Fan Module (Applied to

REXP-1600U-RP, REXP-1200U-RP, REXP-1620U-RP, REXP-1220U-RP)

Insert a fan module into the fan slot until the fan module is fully seated.

Warning: To avoid system overheating, replace the fan module within 3 minutes. Do

not attempt to operate the system without operational fan module(s).

6.2. Remove a Fan Module (Applied to REXP-1620U-RP, REXP-1220U-RP, REXP-1600U-RP and REXP-1200U-RP)

Remove the fan module by grasping and pulling up the fan module from the fan slot.

Chapter 7. Install Power Supply Unit (Applied to REXP-1600U-RP, REXP-1200U-RP, REXP-1620U-RP and REXP-1220U-RP)

Warning: The RAID expansion enclosure supports replacing a redundant power supply unit without turning off the enclosure when the redundant power supply mode is enabled. However, users are strongly recommended to turn OFF the RAID expansion enclosure before replacing the power supply unit to reduce the risk of electric shock.

To replace a failed power supply unit, follow the steps below:

1. Turn off the RAID expansion enclosure.
2. Hold the black handler and press and hold the green button firmly.

1. Unplug the failed power supply.

1. Plug in a new power supply.
