Installation
Rack mounting the 2H252-25R involves the following:
• Attaching the strain-relief bracket
• Rack mounting the 2H252-25R (attaching the mounting brackets and fastening the device to the
rack)
Attaching the Strain-Relief Bracket
Attach the strain-relief bracket to the 2H252-25R as follows:
1. Locate the strain-relief bracket and four 8-32 x 5/16-inch pan-head screws in the rackmount kit.
2. Place the 2H252-25R upside down (as shown in Figure 3-2) on a clean flat surface. Then attach
the strain-relief bracket to the bottom of the 2H252-25R using the four 8-32 x 5/16-inch
pan-head screws.
CAUTION: To ensure proper ventilation and prevent overheating, leave a minimum
clearance space of 5.1 cm (2.0 in) at the left, right, and rear of the 2H252-25R.
WARNING: Before installing the 2H252-25R into a rack, ensure that the rack supports
the device(s) without compromising the stability of the rack. Otherwise, personal injury
and/or equipment damage may result.
CAUTION: Do not attempt to attach the strain-relief bracket with screws other than the
8-32 x 5/16-inch screws included with the 2H252-25R. Use of longer screws may
damage the unit.
