The Cisco ESSE has a bezel that attaches to its front and covers the front panel. This bezel contains two Ethernet indicators, a power indicator, and a power button, and it provides access to the serial port. To remove the bezel, press the tab on each end of the bezel and lift it from the chassis. Figure 1-1 shows the bezel's features.

Front-Panel Features
The Cisco ESSE front panel contains switches (see the "System Switches" section), indicators (see the "System Indicators" section), a CD-ROM drive, and a serial port. To access the front panel, remove the bezel. Figure 1-2 shows the front panel's features.

System Indicators
When troubleshooting your system, you might need to check the status of the indicators on the system's front panel (see Figure 1-2). The appearance and function of these lights are described in Table 1-1.
Table 1-1 System Indicators
Indicator
Color
Function
Power
Green
This indicator lights up when the Cisco ESSE is connected to an AC power source. It blinks when the Cisco ESSE is in sleep mode.
The bezel contains a duplicate of this indicator.
System fault
Amber
This indicator blinks during system startup and when a system fault is detected.
This indicator is not visible with the bezel attached.
Hard drive activity
Green
This indicator blinks when hard drive activity occurs.
This indicator is not visible with the bezel attached.
Ethernet 0 activity / link
Amber
This indicator lights up when the Ethernet 0 port is connected to a network. It blinks when activity occurs on this channel.
The bezel contains a duplicate of this indicator.
Ethernet 1 activity / link
Amber
The Ethernet 1 activity / link indicator lights up when the Ethernet 1 port is connected to a network; blinks when activity occurs on this channel.
The bezel contains a duplicate of this indicator.
System Switches
Refer back to Figure 1-2 to see the location of the switches on the Cisco ESSE front panel. To activate a switch, press the corresponding icon on the front panel. Table 1-2 describes the function of these switches.
Table 1-2 Front-Panel Switches
Switch
Function
Power switch
This switch turns the Cisco ESSE's power on or off. To turn system power off, press and hold this switch for at least 4 sec.
There is a power switch on both the bezel and on the front panel.
Sleep switch
This switch places the system in sleep mode.
This switch is accessible only when the bezel is removed.
Reset switch
This switch reboots the system. If you cannot shut down the Cisco ESSE using the operating system, press the Reset switch.
This switch is accessible only when the bezel is removed.
Nonmaskable interrupt switch
Use this switch only when instructed to do so by Cisco's Technical Assistance Center.
This switch is accessible only when the bezel is removed.
Back-Panel Features
The back panel contains the Cisco ESSE AC power receptacle, Ethernet connectors, and a serial port. Figure 1-3 shows the back-panel features. Do not attach peripheral devices, such as mice, monitors, and keyboards to the Cisco ESSE. It does not support their use.

Serial Ports
The two integrated serial ports on the front and back panels of the system use 9-pin D-subminiature connectors.
Serial Port Connectors
If you reconfigure your hardware, you may need pin number and signal information for the serial port connectors. Figure 1-4 illustrates the pin numbers for the serial port connectors, and Table 1-3 defines the pin assignments and interface signals for the serial port connector.

Ethernet Connectors
Your system has integrated 10/100 Mbps Ethernet connectors. Each Ethernet connector provides all the functions of a network expansion card and supports both the 10BASE-T and 100BASE-TX Ethernet standards.
WarningTo avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.
Network Cable Requirements
The Cisco ESSE Ethernet connectors are designed for attaching an unshielded twisted pair (UTP) Ethernet cable equipped with standard RJ-45 compatible plugs. Press one end of the UTP cable into the Ethernet connector until the plug snaps securely into place. Connect the other end of the cable to an RJ-45 jack wall plate or to an RJ-45 port on a UTP concentrator or hub, depending on your network configuration. Observe the following cabling restrictions for 10BASE-T and 100BASE-TX networks:
For 10BASE-T networks, use Category 3 or greater wiring and connectors.
For 100BASE-TX networks, use Category 5 or greater wiring and connectors.
The maximum cable run length (from a workstation to a concentrator) is 328 ft or 100 m.
For 10BASE-T networks, the maximum number of daisy-chained concentrators on one network segment is four.
Note To avoid line interference, put voice and data lines in separate
sheaths.
