Getting Started Guide 7
4
Insert the switch into the 48.26 cm (19 inch) rack, ensuring that the rack-mounting holes on the switch line
up to the mounting holes in the rack.
5
Secure the switch to the rack with either the rack bolts or cage nuts and cage nut bolts with washers
(depending on the kind of rack you have). Fasten the bolts on bottom before fastening the bolts on top.
NOTICE: Make sure that the ventilation holes are not obstructed.
CAUTION: Make sure that the supplied rack bolts fit the pre-threaded holes in the rack.
Installing as a Free-standing Switch
NOTICE: We strongly recommend mounting the switch in a rack.
Install the switch on a flat surface if you are not installing it in a rack. The surface must be able to support
the weight of the switch and the switch cables. The switch is supplied with four self-adhesive rubber pads.
1
Attach the self-adhesive rubber pads on each location marked on the bottom of the switch.
2
Set the switch on a flat surface, and make sure that it has proper ventilation by leaving 5 cm (2 inches)
on each side and 13 cm (5 inches) at the back.
Connecting a Switch to a Terminal
1
Connect the supplied RS-232 cable to a VT100 terminal or to the serial connector of a personal computer
running VT100 terminal emulation software.
2
Connect the female DB-9 connector at the other end of the RS-232 crossover cable to the serial port
connector on the rear of the switch.
NOTE: If you are installing a stack of switches, connect the terminal to the Master Switch. This switch will light the
Master Switch LED, the top left LED in the array on the front panel. When a stack is powered up for the first time, the
switches elect the Master Switch, which may occupy any location in the stack. If you connect the terminal to a member
switch, you will not be able to use the CLI.
Connecting a Switch to a Power Supply
CAUTION: Read the safety information in the Product Information Guide as well as the safety information for other
switches that connect to or support the switch.
1
Connect the supplied AC power cable to the AC power connector located on the back panel.
Figure 1-2 illustrates where to connect the power cable.
2
To provide a redundant source of power, connect the 12 VDC power cable from a (separately purchased)
PowerConnect RPS-600 for non-PoE switches or PowerConnect EPS-470 for PoE switches to the DC power
connector located on the back panel.
NOTE: Do not connect the power cable to a grounded AC outlet at this time. Connect the switch to a power source
as described in the step detailed in "Starting and Configuring the Switch."
