Chapter 3: Pre-Installation Activities
Configure Ethernet Switch Jumpers
It may be necessary to modify the jumpers on the Ethernet switches. The NPM
basestation uses a configuration of the Ethernet switches that differs from the
manufacturer’s original settings.
NOTE: If the Ethernet switches are pre-installed in the shelves,
then they have already been configured and this procedure is not
required.
Table 3.5 shows the correct settings of the Ethernet switch jumpers.
Jumper Setting Appearance Description
K1 OFF PCI reset. Removing this jumper causes the card
NOT to be reset when the utility bus controller is
reset. This jumper must be left OFF.
K2–K4 ON User-defined. These jumpers must be left ON.
K5, K6 OFF Burn-in mode (K5) and break detect (K6). These
jumpers must be left OFF.
