Cisco MGX 8950 Hardware Installation Guide
Release 3, Part Number 78-14147-02 Rev. A0, November 2002
Chapter 3 Installing a Cisco MGX 8950
Installation Checklist
The Cisco MGX 8950 switch is shipped in one of two hardware configurations:
• Open rack—Modules and cards are shipped pre-installed in a the Cisco MGX 8950 switch and are
tested according to customer specifications before they are shipped. The system is ready for
installation in a customer-supplied open rack. The optional AC power supply tray, air intake plenum,
upper and lower fan trays, and exhaust plenum are packaged separately and will need to be installed
in the rack.
If you are not using a mechanical lift, you will need to remove the modules and cards from the
Cisco
MGX 8950 switch to lessen the weight of the switch prior to installing it in the rack. Follow
the installation procedures in the “Rack Mounted System (without Lift)” column of
Table 3-1.
If you are using a lift to mount the Cisco MGX 8950 switch in a rack, you do not need to remove
the modules, cards, and hardware components. Follow the installation procedures in the “Rack
Mounted System (with Lift)” column of
Table 3-1.
• Cisco cabinet configuration—All components are shipped pre-installed in a Cisco cabinet. Follow
the installation procedures in the “Cisco Cabinet System” column of
Table 3-1.
Note Using a lift to install a fully-loaded Cisco MGX 8950 switch in a rack greatly simplifies the installation
process, because the modules and power supplies do not need to be removed.
Before proceeding with the installation, verify that all the ordered parts are present and in good
condition. Store a record of the parts and serial numbers. If any parts are missing or damaged, contact
your sales representative.
Caution Proper ESD protection is required whenever you handle Cisco equipment. Installation and maintenance
personnel should be properly grounded using ground straps to eliminate the risk of ESD damage to the
equipment. Cards are subject to ESD damage whenever they are removed from the switch.
