Replacing a Cable Restraint on a TX Matrix Three-Input 240-A DC Power Supply
Each three-input 240-A power supply is shipped with the standard cable restraint shown in Figure 1. Two optional cable restraints are shipped in the accessory box.
If your DC power cables are too large or inflexible to fit into the standard cable restraint, we recommend that you remove the standard cable restraint and install the optional cable restraint (see Figure 2) on each three-input 240-A power supply.
 | Note: Before you remove a chassis from a rack or cabinet, you must remove the optional cable restraint from the three-input 240-A power supply. |
