SSG 140 Series Hardware Installation and Configuration Guide
20 Before You Begin
Before You Begin
The location of the chassis, the layout of the equipment rack, and the security of
your wiring room are crucial for proper device operation.
Observing the following precautions can prevent shutdowns, equipment failures,
and injuries:
Before installation, always check that the power supply is disconnected from
any power source.
Ensure that the room in which you operate the device has adequate air
circulation and that the room temperature does not exceed
104° F (40° C).
Allow 3 feet (1 meter) of clear space to the front and back of the device.
Do not place the device in an equipment rack frame that blocks the air vents on
the sides of the chassis. Ensure that enclosed racks have fans and louvered
sides.
Correct these hazardous conditions before any installation: moist or wet floors,
leaks, ungrounded or frayed power cables, or missing safety grounds.
Equipment Installation
You can mount the SSG 140 device into a standard 19-inch equipment rack.
To mount the SSG 140 device, you must have the following items:
Mounting brackets (provided)
Number-2 phillips head screwdriver (not provided)
Four sheet-metal screws that are compatible with the equipment rack (not
provided)
To install an SSG 140 device into a rack, perform the following steps:
1. Attach the left and right mounting brackets to the front of each side of the
chassis as shown in Figure 8.
CAUTION: To prevent abuse and intrusion by unauthorized personnel, install the
SSG 140 device in a secure environment.
NOTE:
If you are installing multiple devices in one rack, install the lowest one first and
proceed upward in the rack.
