Statement 1006
Adhere to the following rack-mounting guidelines and requireme nts when mounting an MGX chassis:
•The chassis and components fit in either a 19-inch wide rack or a 23-inch wide rack. If the chassis
and components are installed in a 23-inch wide rack, extender brackets must be installed.
•When installed in the rack, consider the following:
–
ensure that the vertical hole spacing on the rack rails meets industry standard (EIA/Retma)
mounting hole pattern requirements.
–
it must be mid-mounted between the rack rails
–
it must be front mounted and supported by rear support brackets.
•When situating the mounted chassis, allow enough room to access the back of the unit for cabling
and wiring purposes.
Caution Make sure that mounting the equipment does not create a hazardous condition due to uneven loading.
The equipment rack should be securely supported.
Unpacking the Box
Each Cisco MGX switch or gateway is securely packaged in a shipping box. The MGX switch modules
and cards ship installed in the chassis. If your switch is ordered to be installed in a cabinet as well, the
components are installed in the cabinet (for example, upper and lower fan trays, air intake plenum , and
exhaust plenum).
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.
