Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security.
Statement 1017
Network Modules
You can order the Cisco ASR 901 10G router with the following interface modules.
Note Interface modules are installed and shipped with the router; they are not field replaceable.
Mounting the Cisco ASR 901 10G Router
Note The Cisco ASR 901 10G router is qualified only for horizontal orientation. You should use additional safety measures for vertical orientation.
Each Cisco ASR 901 10G router includes rack-mounting brackets. Using the rack-mounting brackets, you can mount the Cisco ASR 901 10G router in a 19-inch, 23-inch, or an ETSI rack that conforms to the EIA-310-D specification.
Using the two rack-mounting brackets for mounting, you can recess Cisco ASR 901 10G router in the equipment rack. This arrangement provides extra space in front of the router for the cables and allows you to close the doors of racks equipped with front-close doors.
To attach or replace the rack-mounting brackets, see the “Attaching Brackets to the Router” section.
The rack-mounting brackets are slotted to allow the router to be mounted in racks with EIA 1.25-inch (3.175-cm) or WECO 1.0-inch (2.54-cm) hole spacing. When installed in the rack, the Cisco ASR 901 10G router requires one EIA 1.75-inch (4.4-cm) vertical mounting space (or 1 rack unit [RU]) for mounting (see the “Mounting the Cisco ASR 901 10G Router in a Rack” section).
Rack-Mounting Configuration Guidelines
Follow these guidelines to configure the equipment rack:
- When mounting the router to an equipment rack, ensure that the rack is bolted to the floor.
- Because you may install more than one router into the rack, ensure that the weight of all of the routers installed does not make the rack unstable.
- As mentioned in the “Air Flow Guidelines” section, maintain a 6-inch (15.24-cm) clearance on each side of the router to ensure adequate air intake and exhaust.
- Avoid installing the routers in an overly congested rack. Air flowing to or from other routers in the rack might interfere with the normal flow of cooling air through the routers, increasing the potential for overtemperature conditions within the routers.
- Allow at least 19 inches (48.7 cm) of clearance at the front and rear of the rack for router maintenance.
- Follow your local practices for cable management. Ensure that cables to and from the routers do not impede access to perform equipment maintenance or upgrades.
To install the switch in a 19-inch, 23-inch, or a European Telecommunications Standards Institute (ETSI) rack, follow these instructions (The ETSI racks require optional mounting hardware):
Attaching Brackets to the Router
The bracket orientation and the brackets that you use depend on whether you are attaching the brackets for a 19-inch, 23-inch, or an ETSI rack. Figure 3-1 shows the types of mounting brackets.
