How do I correct a loose network connector on a Dell™ PowerEdge™ 2550 server? - KB Article - 147194


PowerEdge™ 2550 server NIC connector.

The I/O opening of the network interface controller (NIC) sits very low in the back of the chassis (Figure 1). This causes the lock mechanism for the network cable to slip out intermittently.


Figure 1



Loop the cable through key ring holder.

The network cable (CAT cable) may have a weak locking lever. Try connecting another cable to the NIC jack in the back of the server.

If another cable is no more secure, loop the cable through key ring holder. (Figure 2)


Figure 2


If the key ring holder does not keep the cable in, perform the following steps to engage the NIC connector father into the rear chassis I/O bracket. (Figure 3)

CAUTION: Before you perform any of the following steps, read the Precautionary Measures warning for your personal safety and to prevent damage to the computer system from electrostatic discharge.

1. Power off the server and open the case.
2. Apply pressure to the top of NIC stack and insert the NIC cable.
