Chapter 3: Site Preparation
It should be verified that the installation site meets the following requirements:
1.
Access to the installation site and the equipment should be restricted to authorized
personnel only.
2.
A readily accessible disconnect device must be incorporated into the building's wiring
between the chassis Power Entry Module (PEM) input terminals and the power source.
3.
The required rating of the disconnect device is determined by the nominal input voltage.
See the table below for a list of permitted nominal inputs and the corresponding disconnect
device ratings.
Nominal Input
Disconnect Device Ratings
-48 V
60 VDC @ 40 A
-60 V
80 VDC @ 40 A
4.
The SC6300 Series Chassis requires at least 5 centimetres (2 inches) of unobstructed
clearance at the side air inlets and outlets to ensure sufficient airflow for the individual
blades.
5.
The installation site must be compatible with the recommended temperatures:
•
The SC6300 Series Chassis has a maximum recommended continuous operating
temperature of 40°C.
•
The chassis is rated to operate during transient conditions from -5° to 55°C for a
maximum of 96 consecutive hours.
•
In closed or multi-rack assembly environments, the local ambient temperature may be
greater than the room ambient.
