2.4 Mounting

The JT-MS-8N2 is equipped with three sets of mounting holes to provide the flexibility

required to accommodate many different types of installation requirements. It may be mounted
either vertically or horizontally on a 19" rack type panel or it may be secured to a wall or bulkhead.

2.4.1 Rack Panel Mounting

Four 8-32 PEM type fasteners are provided along the bottom mounting flange of the JT-MS-

8N3 for mounting to standard 19" rack panels. A single JT-MS-8N2 unit may be mounted
horizontally to a 2U rack panel. Up to seven JT-MS-8N3 units may be mounted vertically to a 7U
rack panel. See 

Figure 2.4.1

 for 2U and 7U rack panel drilling guides.

2.4.2 Bulkhead  Panel Mounting

Four 0.172" diameter mounting holes are provided along the bottom mounting flange and

along the top edge of the JT-MS-8N2 for mounting the unit with the printed circuit board either
parallel to or perpendicular to a bulkhead or wall. If the unit is mounted with the printed circuit
board parallel to the bulkhead or wall, four right angle mounting brackets may be also used to
attach the bottom flange to the wall for additional rigidity.
