Install the PoE DIMM 
Module 
If you are installing the optional PoE DIMM module, use the following instructions. 
Technical Specifications 
The technical specifications of PoE DIMM (Dual In-line Memory Module) are listed in 
Table 5.
Install the PoE DIMM Module
Wear an ESD-protective wrist strap when installing the PoE DIMM modules. 
Insert the Master and Slave DIMM modules in the right sockets. The silk screens on 
the interface card must be consistent with those on the PoE DIMM modules. If the 
modules are wrongly seated, cooling problems may occur, though the PoE module 
can operate normally. 
Note:
With the reverse insertion prevention design, you can only insert the module in the 
right direction.
The PoE DIMM module is only supported on the PoE I/O module.
If no PoE SIMM module is in place, or the module is not fully seated, the interface 
card cannot supply power, even if other functions go well.
The Master and Slave DIMM modules must be used at the same time.
Follow these steps to install the PoE DIMM: 
Check the position of the module. 
Insert the Master DIMM module into the J15 socket of the interface card and the 
Slave DIMM module into the J16 socket. 
Close the locking spring clips until the pins at both ends of the clip snap into the 
notches in the module. 
Mount Chassis
All items required for installation are contained within the packaging. Additional 
power supply modules are shipped separately. Check the packing list. Rack or frame 
mounting screws are not included.
Place unit box in a vertical position near the installation site (equipment cabinet or 
rack).
Carefully remove the crate top, crate sides, and the packing material. If possible, 
recycle the packing crate and the packing material. If not, dispose of properly 
according to local codes and regulations.
