adequately cooled, the Routing Engine shuts down the system by disabling output power
from each PEM.
There is a single air intake in the front of the services gateway. Air is pushed up through
an air filter, through the card cage, and then through the upper fan tray where it combines
in a common exhaust plenum and is exhausted out the upper rear of the system.
Two different types of fan tray are available:
The standard capacity fan tray has six fans and is adequate for services gateways in
which standard-capacity power supplies are installed.
The high-capacity fan tray has 12 fans and is required when high-capacity power
supplies are installed. When high-capacity fan trays are installed, you must also install
the high-capacity air filter tray.
