5.2.1Port Address
Every device that uses the SAS interface has a unique SAS address, and commands use an SAS address to identify each device for I/O operations. Every HDD is assigned a unique SAS address before shipment from the factory, so setting of an address is not required before the HDDs are used.
5.3Mounting HDDs
5.3.1Mounting procedures
Since mounting the HDD depends on the system cabinet structure, determine the work procedures considering the requirements specific to each system. The general mounting method and items to be checked are shown below.
See Section 4.1 for the details of requirements for installing the HDDs.
1)With a system to which an external operator panel is mounted, if it is difficult to access the connector after the HDD is mounted on the system cabinet, connect the external operator panel cable before mounting the HDD.
2)Fix the HDD in the system cabinet with four mounting screws as follows:
•The HDD has 8 mounting holes (both sides: 2 × 2, bottom: 4). Fix the HDD by using four mounting holes of both sides of the HDD or the bottom.
•Use mounting screws of which lengths inside the HDD mounting frame are 2.5 mm ±0.5 mm when the screws are tightened (see Figure 4.3).
•When mounting the HDD, be careful not to damage parts on the PCBA.
3)Confirm the DE is not touching the frame on the system side excluding the screw installing part after tightening the screws. At least 2.5mm of clearance is required between the DE and the frame (see Figure 4.3).
4)When using an electric screwdriver, use the screwdriver that does not apply a force on the HDD that would exceed the HDD specifications.
