Cable Management System | Juniper Networks M10, M5 manual

Cable Management System

The fan tray is hot-removable and hot-insertable, as described in “Field-ReplaceableUnits (FRUs)” on page 3. For instructions on replacing it, see “Replace the Fan Tray” on page 82.

Do not remove the fan tray for more than a about one minute while the router is operating. The fans are the sole source of cooling, and the router can overheat when they are absent.

Cable Management System

The cable management system consists of racks that attach vertically to each side of the chassis at the front, as shown in Figure 11. Pass PIC cables through the openings in the racks to keep the cables organized and securely in place, and to avoid bending optical cables beyond the proper bend radius. The cable management system evenly distributes the weight of a cable, so that it is not subjected to undue stress at the connector.
