3.3.1Rack-mounting (for 19” RETMA racks), regular Magnum 6K25es

Installation of a Magnum 6K25e Fiber Switch in a 19” rack is a simple

procedure. The units are 1U (1.70”) high. When properly installed, the front-mounted LED status indicators should be in plain view and easy to read. Rack-mount installation requires special 19” rack-mounted brackets and screws (included with each Magnum 6K25e unit). These brackets attach to the front sides of the Switch (regular package, i.e., not the Reverse version), which is then typically fastened into a standard 19” RETMA rack as shown here.

The 23” brackets and the ETSI (European metric, approx. 21”) brackets are also available (optional) for rack-mounting of Magnum 6K25e Switches. These brackets are popular in the Telco industry where they are a standard for Central Office rack- mounting purposes. The 23” and the ETSI brackets are mainly used for larger equipment

Fig 3.3.1 Mountings for Magnum 6K25e units rack-mounted in a frame

assemblies in rack-mounting frames where the rack-mount equipment is typically accessed in operation from both sides.

The bracket mounting holes in the sides of the Magnum 6K25e permits it to be mounted in various ways. The same holes fit all three types (19”, ETSI, 23”) of brackets. The mounting for the 23” is illustrated in Figure 3.3.1 below. The brackets may be attached flush with the front, or attached in the center for a set-back mounting which may reduce cabling torque.

The optional 23” brackets and the ETSI (21”) brackets each come as a pair in a
