Installation guide

3.2 Add-On Disk or Tape Drive Positions
Note
A DECArray300 cabinet system with only one Sx300 disk or tape
drive in positions 1 or 5 will have a 25-pound stabilizer plate (weight)
attached to the underneath of the upper cabinet H-stiffener. This is
required to fulfill the requirement of stability in accordance to IEC 950.
2. Center level disk or tape drive installation
When installing an add-on storage element, each storage element is
supported by two chassis retainer brackets (top and bottom).
3. Lower level disk drive installation
Before installing an add-on disk drive in the lower level of the cabinet
(positions 1 or 2), it is recommended to remove the cabinet kick plate
in Section 3.9. Each lower level disk drive is supported by two chassis
retainer brackets (top and bottom). For mounting RA9x storage elements,
you have to remove the cabinet kick plate and mount the cabinet stabilizer
brackets.
4. No more than two storage elements
Do not mount more than two SA70 storage elements per cabinet. You
might violate the FCC or VDE 0878 requirements.
5. EMC finger strips
Some of the SA7x storage elements might have EMC finger strips on top of
the chassis. The EMC finger strips are not necessary for the Sx300 cabinet.
For mounting top positions, remove the EMC finger strips prior to sliding
the storage element into the cabinet.)
3.3 Electrostatic Discharge
Electrostatic discharge (ESD) is caused by the build up and release of static
electricity. An electrical charge from a person or object can damage hardware
components and result in premature device or option failure.
Use the following guidelines when handling static-sensitive components and
modules:
1. Read all instructions and installation procedures including the static
control materials and kits.
