Check Cabling Before Powering On The System; Figure 5-2 Cell Cable Connections - NEC Express5800/A1160 Installation Manual

5.2. Check Cabling Before Powering On the System

Loose or improperly attached cable connectors can adversely affect the system
power-on processes. Check the cabling before applying AC power for the first time.
The following figure shows the cable connections at the rear of the cell.
At the rear of the cabinet, check the following cable connections on each cell:
LAN cable connections (maintenance LAN and partition LAN)
1. Gently pull on the LAN cable to ensure that it is attached completely in the
connector receptacle.
2. If the cable pulls out, check the latching lever. Sometimes the latching lever is
flattened against the connector body and therefore does not latch properly. If
this is the case, pry the lever away from the connector body and reinsert the
connector to see if it latches properly.
3. If the connector still does not latch, try substituting another LAN cable that you
know has a properly latching connector. If the substitute cable latches properly,
the original cable probably has a broken or obstructed connector and should be
replaced.
USB cable connections (partition)
Ensure that the USB connectors are fully seated.
Video cable connection (partition)
