Installing the Cable Management System for Optical FibresInsert an optical cable in a Z9500 port. then route the optical cable up and along the line-card faceabove the switch. Position the cables so they follow the channel marked in the figure below and exitto the right or left, depending on the chassis slot location. The cables should emerge from right andleft side of the panel.Figure 13. Routing Optical Fibres using the Cable Management System1. Rack unit to be installed only for opticalcables 2. Z9500 switchNOTE: When the switch operates in the supported temperature range, LR4 optics can be usedonly in the upper half of the ports on the switch:• Line card 0 — only in ports 12, 16, 20, 36, 40, 44, 60, 64, 68, 84, 88, 92, 108, 112, 116, 132,136, and 140.• Line card 1 — only in ports 12, 16, 20, 36, 40, 44, 60, 64, 68, 84, 88, 92, 108, 112, 116, 132,136, 140, 156, 160, 164, 180, 184, and 188.• Line card 2 — only in ports 12, 16, 20, 36, 40, 44, 60, 64, 68, 84, 88, 92, 108, 112, 116, 132,136, 140, 156, 160, 164, 180, 184, and 188.When the switch operates in a reduced ambient temperature, you can use LR4 optics in anyport. See Port Numbering Convention for an illustration that shows port location.Installing the QSFP+ OpticsThe switch has 132 QSFP+ optical ports, which can be used with breakout cables for 528 small form-factor pluggable plus (SFP+) optical ports.For a list of supported optics, contact your Dell Networking representative or reseller.CAUTION: ESD damage can occur if the components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the switch and its components.Z9500 Installation 35
