Installing the gateway
IMPORTANT:
Keep the packages of the gateway and the components secure for repackaging.
Confirming installation preparations
Before you install the gateway, verify that:
• You have read the chapter "Preparing for installation" carefully and the installation site meets all the
requirements.
• A 19-inch rack has been installed. For how to install a rack, see the rack installation guide.
• The rack is sturdy and securely grounded.
• The rack has enough space to install the gateway and no debris exists inside or around the rack.
• The mounting position of the gateway on the rack has been identified. H3C recommends that you
install the gateway at the bottom of the rack.
• The total height of the devices to be installed in the rack is no higher than the available installation
height of the rack and enough clearance is reserved for cable routing. Make sure the heaviest
device is placed at the bottom of the rack.
• The gateway is ready for installation and has been carried to a place near the rack and convenient
for moving.
Attaching slide rails to the rack
If the rack has slide rails, skip this section.
Before you attach slide rails to the rack, verify that:
• The slide rails can support the weight of the gateway. For the weights of the M9000 gateways, see
"Appendix A Chassis views and technical specifications."
H3C recommends that you order the H3C slide rail LSTM2KSGD0. The slide rail has an
adjustment range of 500 mm (19.69 in) to 800 mm (31.50 in).
• When the gateway is installed in an enclosed cabinet, the distance between the front rack posts
and the front door must be at least 100 mm (3.94 in) for installing cable management brackets, and
the distance between the front rack posts and the rear door must be at least 660 mm (25.98 in) for
the chassis with cards installed.
• To ensure stability of the rack, install the slide rails to the lowest possible position when installing a
single gateway on the rack. To install multiple devices on the rack, mount the heaviest device at the
bottom of the rack. For the height and other specifications of the M9000 gateways, see "Appendix
A Chassis views and technical specifications."
Slide rail installation varies with rack type. The following installation procedure is for your reference only.
