Figure 3-2 Attaching the Cable Guide
Step 3 Use an M4.0x20mm Phillips screw to fix the cable guide to the mounting bracket. Do not over-tighten
the screw.
Step 4 Repeat Steps 2 and 3 to attach the other cable guide.
Note If you find it awkward to insert the screw while holding the cable guide in place, you can first insert the
screw only far enough so that it does not fall out. Then, using the slot in the mounting pillar of the cable
guide, slide the cable guide into place around the screw. Finally, tighten the screw to fix the cable guide
to the mounting bracket.
Connecting the Chassis Ground and Power
Before you connect power or turn on power to the Cisco ASR 901 router, you must provide an adequate
chassis ground (earth) connection to your router.
Grounding the Cisco ASR 901 Router
The Cisco ASR 901 router provides a grounding point on the rear of the unit for a 2-hole lug.
To ensure the chassis ground connection that you provide is adequate, you need the following parts and
tools:
• Ratcheting torque screwdriver with Phillips head that exerts up to 15 pound-force inches (lbf-in) of
pressure for attaching the ground wire to the router.
• Crimping tool as specified by the ground lug manufacturer
• 16-AWG copper wire for the power cord
• Wire-stripping tools appropriate to the wire you are using
Caution Before making connections to the Cisco ASR 901 router, ensure that you disconnect the power at the
circuit breaker. Otherwise it may result in severe injury or damage to the router.
