3.4.2 Rackmount Installation
Rackmount installations must be within reach of the network cabling and
meet the requirements listed below:
• Locate the 2H22-08R within seven feet of an appropriately grounded
power source and an unrestricted surface area as shown in
Figure 3-1
that meets the power supply requirements listed in Appendix A .
• Maintain a temperature of between 5°C (41°F) and 40°C (104°F) at
the installation site with fluctuations of less than 10°C (18°F) per hour.
The 2H22-08R is shipped with a strain-relief bracket for cable
management. The rackmount kit contains the rackmount brackets and
mounting screws for installing it in a 19-inch rack.
Attaching the Strain-Relief Bracket
Use of the strain-relief bracket is optional, but recommended to reduce
cable damage and maintain an orderly environment. Attach the
strain-relief bracket to the front of the 2H22-08R as follows:
1. Locate the strain-relief bracket and four 8-32 x 3/8-inch pan-head
screws in the rackmount kit.
2. Attach the strain-relief bracket to the bottom of the 2H22-08R using
the four 8-32 x 3/8-inch pan-head screws (
Figure 3-2 ).
WARNING
Before installing the 2H22-08R 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 3/8-inch screws included with the
2H22-08R. Use of longer screws may damage the unit.
