• At least 2 ft (60.96 cm) in front of the power tray to insert power modules.
• Maintain at least 24 inches (61 cm) of clearance in front of and behind the chassis for maintenance after
installation.
• For the Cisco ASR 9910 Router, maintain at least 30 inches (76.2 cm) of
clearance behind the chassis for maintenance after installation (for removal
and installation of the rear-mounted fan tray).
• For the Cisco ASR 9904 Router, maintain at least 26 inches (66.0 cm) of
clearance behind the chassis for maintenance after installation (for removal
and installation of the rear-mounted fan tray and air filter).
• For the Cisco ASR 9006 Router, maintain at least 25 inches (63.5 cm) of
clearance behind the chassis for maintenance after installation (for removal
and installation of the rear-mounted air filter).
Note
• To mount the router between two posts or rails, the usable aperture (the width between the
inner
edges
of the two mounting flanges) must be at least:
• 17.50 inches (44.45 cm) for the Cisco ASR 9010 Router.
• 17.75 inches (45.09 cm) for the Cisco ASR 9006 Router, Cisco ASR 9904 Router, and Cisco ASR
9906 Router.
• 17.60 inches (44.70 cm) for the Cisco ASR 9910 Router.
• To mount the router in a 4-post rack, the usable aperture (the width between the
inner
edges of the two
mounting flanges) must be at least 17.75 inches (45.09 cm) for the Cisco ASR 9922 Router or Cisco
ASR 9912 Router.
• When fully populated with cards, the router can weigh up to 1038 pounds (470.28 kg). To maintain
equipment rack stability and to ensure your safety, the rack is provided with stabilizing devices. Make
sure you install the stabilizers before installing the router.
• If you use a telco-style rack, the weight of the chassis is cantilevered off of the two rack posts. Make
sure that:
• Weight of the router does not make the frame unstable.
• Frame is bolted to the floor and is secured to the building structure using either wall brackets or
overhead brackets.
• When mounting the router in a telco-style rack or 4-post rack, be sure to use all of the screws provided
to secure the chassis to the rack posts.
• Install the cable-management brackets included with the router to keep cables organized. Be sure to:
• Use appropriate strain-relief methods to protect cables and equipment connections.
• Make sure that cables from other equipment installed in the rack do not restrict access to the card
cages.
