● 12-port SPI4.2 Gigabit Mac
● 4 x front-accessible Gigabit (data) ports
NOTE
Replacing the NPE alters the MAC addresses of the system data ports. New MAC addresses are advertised on the
network in relation to the system interface IPs. You must ensure that no specific network topology is in place which
can be affected by the MAC address change to the network. The IP addresses for the system do not change.
Summit WM Controller WM200/2000 power and maintenance
procedures
This section provides procedures to power off and power on the system when performing maintenance.
Use the following information to help eliminate system problems.
Tools and equipment required
Use the following tools and equipment to power on the system and verify system power:
● ESD kit
● Phillips screwdriver
Maintaining the ESD wrist strap
The ESD wrist strap and cord must operate properly to guard against ESD damage and electrical
shocks. The wrist strap and cord assembly has a 1-megohm resistor; if the resistor fails, there is no ESD
protection.
NOTE
Check the wrist strap weekly to ensure proper ESD protection.
To test the ESD wrist strap using a DMM:
1 Set the ohmmeter to 2-megohm resistance (see Figure 18).
2 Connect the DMM black lead to the alligator clip at the end of the cord.
3 Contact the DMM red lead to the plate on the inner surface of the wrist strap.
4 Check the resistance reading on the meter. The meter reading must be between 0.80 and 1.20 mega
ohms.
5 Replace the wrist strap and cord assembly if the reading is not within the allowable range.
