Confirming installation preparations
Before you install the router, verify that:
•
You have read "Preparing for installation" carefully.
•
All the requirements described in "Preparing for installation" are met.
Rack-mounting the router
CAUTION:
For good ventilation and easy maintenance, reserve a minimum clearance of 1200 mm (47.24 in)
between the rack and walls or other devices.
Attaching slide rails to the rack
CAUTION:
The router is high and heavy. To ensure rack and router stability, install slide rails at the location
marked "1RU" on the rack. Make sure the load-bearing plane of the slide rails is perpendicular to the
four rack posts.
To rack-mount the router, select and attach slide rails to the rack. See Table2-1 for the slide rail
requirements.

(Optional) Installing PDUs
If you are to use PDUs, install PDUs on the rack before installing the router in the rack. Two PDU
brackets are required for installing a PDU on the rack.
To install PDUs:
1. Determine the PDU installation locations on the rack posts.
Make sure the installation of PDUs does not cross the rack beams, does not affect fan tray
installation, removal, or maintenance, and allows easy cable routing.
2. Install cage nuts at the PDU bracket installation locations, as shown by callout 1 in Figure2-3 .
3. Use two M6 screws to secure a PDU bracket to the rack post, as shown by callout 2 in
Figure2-3 .
4. Attach the PDU to the PDU brackets. See callout 3 in Figure2-3 .
