Detailed Answer:
Cisco IOS privilege levels determine the commands a user can execute. There are several privilege levels, each granting access to a different set of commands. The most common are:
User EXEC Mode (Level 1): This is the default mode when you initially log in. Limited commands are available, primarily for basic system monitoring and showing information. You can't configure anything at this level. Common commands include:
show version (Displays system information)show ip interface brief (Displays interface status)show running-config (Displays the current running configuration – read-only)show clock (Displays the system clock)enable (Moves to privileged EXEC mode)Privileged EXEC Mode (Level 15): Accessed by using the enable command. Provides access to a significantly wider range of commands, including configuration commands. However, it still doesn't allow changes to the actual configuration file. Commands like configure terminal are needed to modify the config.
configure terminal (Enters global configuration mode)copy running-config startup-config (Saves the running configuration to the startup configuration)debug commands (For troubleshooting; various sub-commands available)show commands (More detailed versions than those in User EXEC)Global Configuration Mode: Accessed via the configure terminal command from Privileged EXEC mode. Allows modification of the device's configuration. The commands here affect global settings.
hostname <name> (Sets the device's hostname)interface <interface> (Configures a specific interface)ip routing (Enables IP routing)access-list (Configures access control lists)Interface Configuration Mode: Accessed from Global Configuration mode by using the interface command followed by the interface type and number (e.g., interface GigabitEthernet0/0). Commands here specifically configure the characteristics of a network interface.
ip address <ip-address> <subnet-mask> (Assigns an IP address and subnet mask)description <text> (Adds a descriptive label to the interface)shutdown (Disables the interface)no shutdown (Enables the interface)There are other modes within the configuration hierarchy (like line configuration mode, VLAN configuration mode etc.), but these are the fundamental levels.

Troubleshooting a Hayward Salt Cell Showing Incorrect Salt Level Readings
There are several reasons why your Hayward salt cell might be displaying an inaccurate salt level. Let's troubleshoot this step-by-step:
Clean the Salt Cell: The most common cause is a dirty or scaled salt cell. Salt buildup, minerals, and other debris can interfere with the conductivity readings. Follow Hayward's instructions for cleaning your specific cell model. This typically involves removing the cell, gently brushing away any deposits with a soft brush (avoiding abrasive materials), and rinsing it thoroughly with clean water. Pay close attention to the flow-through passages.
Check the Cell's Wiring and Connections: Loose or corroded connections between the salt cell and the control panel can lead to faulty readings. Inspect all wires for damage and ensure they're securely connected. Tighten any loose screws or connectors. Sometimes, simply re-securing the connections can resolve the issue.
Verify Salt Level in the Pool: Use a reliable pool water test kit (not the salt cell's reading) to independently verify your pool's actual salt concentration. If the test kit shows a significant discrepancy from the salt cell's reading, the cell is likely malfunctioning.
Inspect for Leaks: Examine the salt cell and its surrounding plumbing for any leaks. Leaks can dilute the salt concentration near the cell's sensors, producing inaccurate readings. Repair any leaks promptly.
Check the Control Panel: If the problem persists despite cleaning and checking the connections, the control panel itself might be faulty. This is less common but possible. Consult the Hayward troubleshooting guide for your specific control system or contact a pool service professional for assistance.
Cell Failure: After thoroughly checking all the above, it's possible the salt cell itself has failed. A failed cell will need to be replaced. This is determined if you have thoroughly ruled out the other possible causes.
Important Note: Always disconnect the power to the pool equipment before performing any maintenance or troubleshooting on the salt cell or control panel.
