Cable management
Cabling guidelines
• Keep cables away from major h eat sources like the heatsink assembly.
• Do not jam cables on top of expansion cards or memory modules. Printed circuit cards are not
designed to withstand excessive pressure.
• Keep cables clear of sliding or moveable parts to prevent cutting or crimping.
• Do not sharply bend any cable. A sharp bend can break the internal wires.
• Never bend a SATA/SAS data cable tighter than a 30 mm (1.18 in) radius.
• Never crease a SATA/SAS data cable.
• Do not rely on componen ts like the drive cage, p ow er supply, or computer cover t o push cables
down into the chassis.
• Use supplied cable management straps to secure cables.
NOTE: Always follow good cable m a n agement practices when working inside the comp uter.
To remove power supply power cables and RPS from system board connectors respectively use the
following steps:
1. Squeeze on the top of the retaining latch attached to the cable end of the connector.
2. Grasp the cable end of the connector and pull it straight up.
CAUTION: When removing cables, always pull the connector - NEVER pull on the cable. Pulling the
cable could cause cable damage and result in power supply failure.
