7750 SR-a Chassis Features
The 7750 SR-a family of routers has two chassis models: the 7750 SR-a4 and 7750 SR-a8.
Both chassis are designed for a 19-in. (482.6 mm wide by 300 mm deep) EIA-310 rack with
universal spacing. The chassis can also be installed in an ETSI 600 mm wide by 300 mm deep
rack using the adapter brackets that are included with the chassis.
Each 7750 SR-a4 and 7750 SR-a8 router chassis is shipped with a backplane, card cage, and
factory-installed air filter. Mounting brackets for the chassis are integrated so that the chassis
can be mounted in a standard EIA-310 rack.
The AC or DC PSU, CPM-a, IOM-a, MDA-a, and fan tray components are packaged and
shipped separately. Impedance panels, which are ordered separately, are required to cover
empty slots to ensure cooling, for EMI containment during operation, and to prevent dust
accumulation.
The chassis can be installed horizontally or vertically in the rack.
•
In a horizontal installation, card slots are oriented horizontally; the fan tray and air
filter are oriented vertically, and the airflow is side to side.
•
In a vertical installation, card slots are oriented vertically; the fan tray and air filter
are oriented horizontally, and the airflow is front to back. A vertical installation
requires the Vertical Rack Mount Kit (3HE09608AA), which is sold separately.
Refer to the Vertical Rack Mount Kit Installation Guide (3HE10249AAAA TQZZA
Edition 01) for information about how to mount the 7750 SR-a4 and 7750 SR-a8
routers vertically.
Access to all 7750 SR-a components is from the front of the chassis.
See the following subsections for more information about each chassis.
