16 CHAPTER 4: INSTALLATION AND TESTING
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:
1 Check the position of the module.
2 Insert the Master DIMM module into the J15 socket of the interface card and the
Slave DIMM module into the J16 socket.
3 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.
1 Place unit box in a vertical position near the installation site (equipment cabinet or
rack).
2 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.
