Use this guide to quickly set up your Enterasys SecureStack
switch. For complete instructions, see the SecureStack A2 Hardware
Installation Guide associated with your switch.
Electrical Hazard: Only qualified personnel should
perform installation procedures.

Handling the Switch

™
A2
Caution: The switch can be damaged by electrostatic
discharge.
To prevent electrostatic damage, attach an electrostatic discharge
(ESD) wrist strap to your wrist before handling the switch.

Unpacking the Switch

Unpack the switch as follows:
1. Remove the packing material protecting the switch.
2. Remove the switch from the non‐conductive bag.
3. Perform a visual inspection of the switch for any signs of
physical damage. Contact Enterasys Networks if there are any
signs of damage. See "Getting Help" for more information on
contacting Enterasys Networks.
Connecting Power to the Switch
Note: Enterasys Networks recommends installing
any components before powering on your switch.
You can connect an A2 switch to a single, primary source of power,
or to two sources of power for redundancy.
The following redundant power supplies are available for purchase
from Enterasys Networks for connection to an A2 switch:
• C2RPS‐PSM, a 150 watt DC power supply capable of providing
power to a fully‐loaded non‐PoE switch.
• C2RPS‐POE (A2H124‐24P and A2H124‐48P only), 500 watt DC
power supply for PoE switches.
To power‐up your A2 switch:
1. If you are connecting a redundant power supply, attach the
C2RPS‐PSM cable (for non PoE) or C2RPS‐POE cable (for PoE)
from your redundant power supply to the A2 switch's
redundant power connector.
2. Attach the AC power cord to the A2 switch's AC input power
connector.
3. Plug the redundant power supply (if applicable) and the A2
switch AC power cords into dedicated, grounded AC outlets.
Note: To take full advantage of redundancy, each power
supply should be plugged-in to a separate, dedicated AC
outlet.
4. Once power is connected, verify that the RPS power LED turns
green, and the CPU (system) LED turns amber until the A2
switch finishes its initialization.
5. If the initialization process is successful, the CPU LED turns
green. If the CPU LED does not turn green, refer to the
SecureStack A2 Hardware Installation Guide associated with your
A2 switch for troubleshooting information.
Completing the Setup and Downloading the Latest
Firmware
Once you have connected power to the A2 switch and verified LED
activity, you can complete the setup process as follows. Refer to the
SecureStack A2 Hardware Installation Guide associated with your A2
switch for more information.
1. Determine the latest A2 firmware version by visiting the
Enterasys Networks download site at:
http://secure.enterasys.com/services/support/downloads/software
2. Connect the switch to the network.
3. Connect a management station to the console port.
4. Verify that the network devices connected to the switch ports
are powered on, and that each link/activity LED is on (solid
green or blinking green).
5. At the device connected to the console port, perform the
following:
a. Enter admin for Username.
b. At the Password prompt, press ENTER (RETURN).
c. At the command prompt, determine if the latest firmware
image is loaded on the switch by entering this command:
show version
d. If the output (under FW Version) displays an older version
number than that determined in Step 1, download and
activate the new version as directed on the download website.
(Alternatively, you can use the CLI command listed in
Table 1.)
Basic Setup Commands
Table 1 lists CLI commands that are required for setting up the A2
switch with the latest firmware. Table 2 lists additional basic
configurations for your A2 switch. For the complete list of CLI
commands, see the Enterasys SecureStack A2 Configuration Guide.
