The MRU supports two types of mounting installations:
• 19 – in rack installation ( see Section 6.1.2.1)
• Wall mount installation (see Section 6.1.2.2)
• Outdoor installation – the MRU can be installed in a separately ordered outdoor enclosure; Refer to Section 0 for
instructions on how to install the MRU in a Purcell cabinet (Flexsure®12-2420).
6.1.2.1 Rack Installation
Note the following:
• MRU chassis requires 6U rack height availability
• Rack nuts and screws not provided
To install MRU in rack
Determine the location of the MRU in the rack while considering additional units (e.g. power supply).
1. Referring to Figure 6-1, secure the units’ rack ears to the rack frame as follows:
− Insert two screws half-way into the rack frame (one on each side)
− Position the bottom half slots of the chassis rack ears on to the screws
− Secure the unit in the rack via the remaining applicable bracket holes using the appropriate rack nuts and screws
