Install Guide

Fans

The VEP4600 comes from the factory with one or two PSUs and four or five fan modules installed in the platform, depending on the

configuration. The fan modules and the power supplies, which have integrated fans, are hot-swappable.

In addition to the power supply modules, you can order fan modules separately to install.

The VEP4600 supports airflow from the I/O side to the PSU side. The red indicator is the normal airflow direction.

Environmental factors can decrease the amount of time required between fan replacements. Check the environmental factors regularly.

An increase in temperature and/or particulate matter in the air might affect performance; for example, new equipment installation.

CAUTION: Check the fans at six-month intervals; replace them as necessary. Regularly monitor the speeds of the fans

to accurately determine replacement intervals.
