Cisco 1721 Router Hardware Installation Guide

Step 2 Hang the router on the screws with either the left side or right side mounting

brackets so that

• The LEDs are visible to the user—Because the LEDs indicate the router

operating status, they need to be easily visible.

• The power supply does not hang from its cable—If the power supply is not

supported, it might disconnect from the cable that connects it to the router.

Caution If you install the screws in drywall, use hollow wall anchors (1/8 inch

by 5/16 inch) to secure the screws. If the screws are not properly anchored, the

strain of the cables connected to the router rear-panel connectors could pull the

router from the wall.

Stacking the Router

You can stack one Cisco 1721 router in a four-device stack, along with other Cisco

products designed to be stacked with the router. You can stack each device directly

on top of another device.

Note The Cisco 1721 router is not shipped with the stacking equipment described

in this section; however, the equipment is included with all other Cisco

products that are designed to be stacked.

Each Cisco product designed to be stacked with the router comes with a stacking

clip and a fastener for keeping the multiple devices together in a stack. Before you

stack the devices, assemble the clip and fastener as shown in Figure 2-8.
