Handling the Switch

™

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
