4.2 PRE-INSTALLATION TEST
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.
