# Installing a Cable-Management Bracket on ERX7xx Models

You can install a cable-management bracket to accommodate cables of different sizes on ERX7xx models. See Figure 47.

- For wider X.21/V.35 cables, mount the bracket in the last row of perforation holes in the chassis so that the bracket allows for maximum spacing (A).
- For smaller cables, mount the bracket closer to the front of the chassis (B).

Use two (2) #10 self-tapping screws to secure the bracket.
