Installation
Guidelines for the Rackmount Installation
The installation site must be within reach of the network cabling and meet
the requirements listed below:
• An appropriate grounded power receptacle must be located within
seven feet of the device. (This requirement does not apply to the
2M46-04RDC.)
• 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.
To install the 2M46-04R/04RDC in a 19-inch rack, Cabletron Systems
includes an accessory kit containing the rackmount brackets, mounting
screws, and a strain-relief bracket for cable management.
Attaching the Strain-Relief Bracket
Attach the strain-relief bracket to the front of the 2M46-04R/04RDC as
follows:
1. Locate the strain-relief bracket and four 8-32 x 3/8-inch pan-head
screws in the rackmount kit.
2. Place the 2M46-04R/04RDC upside down (as shown in Figure 3-2) on
a clean flat surface. Then attach the strain-relief bracket to the bottom
of the 2M46-04R/04RDC using the four 8-32 x 3/8-inch pan-head
screws.
WARNING
Before installing the 2M46-04R/04RDC 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
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 2M46-04R.
!
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
2M46-04R/04RDC. Use of longer screws may damage the unit.
