Cisco ASR 903 Installation Guide

Step 1 Position the chassis in the rack as follows:
• If the front of the chassis (front panel) is at the front of the rack, insert the rear of the chassis between the mounting
posts.
• If the rear of the chassis is at the front of the rack, insert the front of the chassis between the mounting posts.
Step 2 Align the mounting holes in the bracket (and optional cable guide) with the mounting holes in the equipment rack.
Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the
chassis can deform or damage the handles.
