Quick Reference Guide supplied with the UEM. 2.2.5 Mounting Hints The CrossFire 8720 Switch can be mounted in a standard 19-inch rack or cabinet, or can be mounted on any flat surface such as a tabletop. The installation area should be near a power source and should have enough room around the front and back panels for cabling and access to controls.
Close the cap again to conceal the screws. Table-top Mounting The CrossFire 8720 Switch operates at a low noise level, which makes it suitable for a work area or almost anywhere with a large enough flat surface such as a table, desktop, or similar area.
1. If you have an expansion module (UEM), follow the installation instructions shipped with the UEM, then go to the next step in this procedure. 2. Following the CrossFire 8720 Cabling Chart provided by your network administrator, connect the cables between the switch and other devices as illustrated in figure 3.
7. If the switch is rack-mounted, thread the switch end of the cables through a cable management bracket, if one is present on your rack. See Applying Power on page 16. Figure 4. Connecting Using Building Wiring CrossFire 8720 Fast Ethernet Layer 3 Switch, v. 1.00.02, P/N: 710001800 Installation...
There are no user serviceable parts inside the CrossFire 8720 Switch. Internal upgrades or service should be performed by qualified personnel only. Warning: The CrossFire 8720 Switch does not have an on/off switch. Power is on when the unit is plugged into a power source. Unplug the power cord before you work on a system that does not have an on/off switch.
The RMON interface - used to monitor and analyze the switch operation with a standard RMON SNMP application. For more information, see RMON Support in the Olicom CrossFire 8720 Fast Ethernet Layer 3 Switch Reference Guide. Each interface consists of a series of management features accessed through a menu-driven screen system.
Factory IP settings for the switch are: IP address: 192.0.2.1 IP mask: 255.255.255.0 To change these settings, refer to the IP Switching sections of the Olicom CrossFire 8720 Fast Ethernet Layer 3 Switch Reference Guide. 3.2.3 To Start a Web Management Session 1.
