DLP- E143 Install the Wide CRMs
DLP-E143 Install the Wide CRMs
Note If you are installing CRMs on more than one shelf, it is easiest to install the lowest CRMs first.
Note If your site uses under-floor cabling, mount the CRMs on the sides of the bay directly next to the shelf
below the node for which you want to route cables. (For instance, if you are routing cables that originate
in the top shelf, mount the CRMs that will route those cables on the sides of the bay at the middle shelf
level.)
Step 1 To install the lower latch bracket for the right-side CRM, line up the holes with the holes on the shelf
where you removed the plastic cable radius.
Step 2 Screw the two screws through the brackets into the shelf.
Step 3 Repeat for the right-side CRM’s top latch bracket.
Step 4 Repeat Steps 1 through 3 for the left-side latch brackets.
Step 5 On the front right edge of the bay, locate the three screw holes that will be used to secure the right-side
CRM to the bay. Insert a #8 screw in the top hole and turn five revolutions. Do not tighten the screw
completely, but make sure it is started enough so that it is secure in the bay (Figure17-3).
Note Only the left-side CRM front door has the cutout and label for the ESD jack.
Step 6 Repeat for the two remaining screws on that side of the bay.
Purpose This task installs the wide CRMs.
