Cabletron Systems SEHI-22FL Mode D'Emploi

Chapter 4: Installation

The SEHI is equipped with an NVRAM reset switch (Figure 4-1) located 
behind the grillwork on the side of the hub. Ensure that this switch is in 
the DOWN position by looking in through the grillwork on the right side 
of the hub. If the switch is UP, move it into the DOWN position with a 
non-metallic tool. Do not remove the chassis cover to perform this 
operation. Leaving the switch in the UP position results in user-installed 
parameters such as IP address and Community Names being cleared from 
NVRAM whenever the SEHI loses power and/or is reset. See Chapter 6, 
Section 6.4, for detailed instructions on setting the NVRAM switch.

The SEHI may be installed on a tabletop or shelf, or in a 19-inch rack, and 
configured as a standalone or stacked hub. 

Refer to Section 4.3.1 for information concerning a tabletop or shelf 
installation. Section 4.3.2 describes the rackmount installation.
