2.3 INSTALLING THE ELS100-16TX

Rack-Mounting an ELS100-16TX

Table 2-3 describes some general considerations you should be aware of before mounting an ELS100-16TX in a rack assembly.

Table 2-3. General Considerations for Mounting an ELS100-16TX

Consideration	Discussion

Temperature	Since the temperature within a rack assembly
	may be higher than the ambient room
	temperature, make sure the rack environment
	temperature is within the Operating
	Temperature range speciﬁed in Appendix A.

Air Flow	Make sure there is at least 2 inches (or more)
	on both sides of the ELS100-16TX to allow for
	adequate air ﬂow.

Mechanical Loading	Do not place equipment on top of a rack-
	mounted ELS100-16TX.

Circuit Overloading	Make sure the power supply circuit to the
	rack assembly is not overloaded.

Grounding	Rack-mounted equipment should be
(Earthing)	grounded. In addition to the direct
	connections to the main power supplies, make
	sure all the other supply connections are also
	grounded.

The ELS100-16TX can be rack-mounted in a standard 19-inch equipment cabinet. To mount the ELS100-16TX in a rack assembly, apply the following steps:

1.Attach the rackmount brackets to either side of the ELS100- 16TX chassis, as shown in Figure 2-3.
