Disk Module Installation

2.6.1 Blank Module Requirement
The SS8460 enclosures require blank modules to complete any partially populated rows.
If two rows are full, the third has seven disk modules, and the last three rows are empty, then:
• The partially populated row #3 must have seven blank modules.
• The completely empty rows #4, #5, and #6 do not need any blank modules.
2.6.2 Procedure
NOTE : When the enclosure is powered on, the cover should only be open for
5 minutes out of every 60 minutes to maintain proper cooling. DDN
recommends that the initial loading of 84 disk (or blank) modules, which is
likely to take more than 5 minutes, be done with the power to the enclosure
off.
Follow these steps to install a disk module:
1. Squeeze the two release tabs on the front of the enclosure to disengage the latches.
Then slide the enclosure out from the rack and keep pulling until the enclosure locks
and you hear a clicking sound (Figure 33).
2. Swing up both cover release handles to disengage the locks (Figure 34). Lift up the
cover. The cover is equipped with constant torque hinges which allow the door to
remain in place at any open position and prevent it from being dropped.
