4.2.5 Mounting Chassis in 19-IN Rack
Note the following:
• The mounting procedure is the same for all chassis types (i.e. HEU, OIU and IHU).
• For IHUs – the IHU cable management tray, consisting of tray with routed ERFC cable and door sleeve, should be
assembled before the unit is mounted onto the rack. See Section 4.2.2.
• For HEU/OIU – the cable management tray can be assembled before after the chassis installation. See Section
Error!
Reference source not found. for details on how to assemble.
• Each chassis requires 4U rack height availability.
• Rack nuts and screws not provided (since that depends on the rack type).
To mount the chassis
1. Determine the location of the chassis in the rack while considering additional headend units and the lengths of the available
ERFC cables to be connected between the HEUs, OIUs and IHUs (provided with each HEU).
Note: In the IHU chassis, the ERFC cable is pre-routed through its’ cable tray
Figure 4-9 and Figure 4-10 illustrate the optimal rack installations for a maximum 4x4 HEU-OIU configuration in shared
and dedicated equipment scenarios.
