3.1 Site Preparation
3.1.1 Selecting a Site
Mount the 7210 SAS-M in a standard 19-inch equipment rack or on a flat surface.
When you mount your switch on a flat surface, ensure that the four rubber feet are
installed on the bottom of the chassis.
The site should be a weather-protected and temperature-controlled location, and
should include the following criteria:
• The 7210 SAS-M supports temperature operation from 32 to 122ºF (0 to
50ºC). The 7210 SAS-M 24F 2XFP ETR variant supports extended
temperature operation from –40 to 149ºF (–40 to 65ºC). Humidity levels in the
site must be controlled to ensure a relative humidity level between 5 and 95%
(non-condensing) for both the 7210 SAS-M and 7210 SAS-M 24F 2XPF ETR.
• Provide adequate space on the front and two sides of the unit to enable
servicing and proper air flow.
• Ensure that the installation site is secure and only authorized service
personnel are allowed to access the unit (IEC 60950 safety requirement).
For more information about installation site assessment, see section 10.
3.1.2 Ethernet Cabling
To ensure proper operation in a network, make sure that the cables are suitable for
100/1000 fiber-optic or 10/100/1000 Base-T copper operation. Make sure your
installation complies with the following guidelines:
• Cable type: shielded twisted pair (STP) cables with RJ-45 connectors;
Category 3 or better for 10 Base-T, Category 5 or better for 100 Base-Tx, and
Category 5, 5e or 6 for 1000 Base-T.
• Make sure cables are not damaged and RJ-45 connectors are seated.
• Avoid installing copper cables close to strong electromagnetic fields
generated by electric generators, elevator motors, or similar heavy electric
machines.
• Make sure you only use SFPs and XFPs that are supported by Nokia.
