Chapter5 Installing the Cisco MGX Switch or Gateway
Installing the MGX 8850 (PXM1E/PXM45) Switch, MGX 8850/B or MGX 8880 Media Gateway
Note Using a lift to install a fully loaded MGX 8850, MGX 8850/B, or MGX 8880 system in a rack greatly
simplifies the installation process, because the modules do not need to be removed from the chassis.
Before proceeding with the installation, verify that all of 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. Ins tallation and maintenance
personnel should be properly grounded through the use of ground ing straps to eliminate the risk of ESD
damage to the equipment. Modules are subject to ESD d amage whenever they are removed from
the chassis.
