7750 SR-a4 and SR-a8 Installation Guide
The fans are controlled by the system software, and their speed is set according to the
environmental temperature surrounding the router. Allow at least 3 in. (7.6 cm) of clearance
on each side of the rack to ensure adequate air intake and exhaust.
The fan LED located on the front panel of the fan tray indicates the tray status: normal online
(green), fault (amber), or offline (not lit if there is no power to the fans). See
for more information.
There are no field replaceable parts in the fan tray. The entire fan tray must be replaced if a
component, such as a single fan, fails. See
Removing and Replacing a Fan Tray on page 185
for more information.
Fan trays must always be installed and fully operational while the 7750 SR-a chassis is
powered.
Air Filters
Air filters are chassis specific:
•
The 7750 SR-a4 chassis requires the 7750 SR-a4 filter.
•
The 7750 SR-a8 chassis requires the 7750 SR-a8 filter.
Each chassis has one air filter slot that is located on the right side of the front panel.
The air filter has two parts: a reusable metal carrier, and a field replaceable filter. The reusable
carrier and one air filter are shipped installed in the chassis.
