Rack Mounting the MGX 8220 Units
Parts Checklist
Before proceeding with the installation, use the parts checklist to verify that all the parts you ordered
are present and in good condition.
Plug-in cards may be shipped already installed in the shelf or under separate cover. The exact number
of cards will vary from site to site, depending on the selected configuration. The MGX 8220 shelf is
shipped with all unused front and back slots covered with inserts which prevent radio frequency
emissions and ensure proper air flow through the shelf. The unit must not be operated with any
unused slots left uncovered.
NoteAn inventory of the installed cards is taped to the MGX 8220 shelf showing serial number,
revision number, and slot number for each card. After verifying the cards, store the inventory for
future reference.
Rack Mounting the MGX 8220 Units
MGX 8220 modules are designed to be rack mounted as follows.
Horizontal Positioning
MGX 8220 modules are designed to be mounted to two vertical rack mounting rails. A front
mounting rail is used as one mounting point using the flanges provided at the front of each
MGX 8220 module. A second rail, either at the rear of the rack or at an intermediate position, is used
for the second mounting point (mounting brackets are provided for attaching the module to the
second rail). The allowable positions for intermediate rails is shown in Figure7-1.
