Use this guide to quickly set up your Enterasys SecureStack
B‐Series switch. Enterasys Networks recommends that you refer
to the Enterasys SecureStack B‐Series Hardware Installation Guide
associated with your switch for specifications and safety
warnings.

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 tape seal on the non‐conductive bag to remove the
switch.
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

Electrical Hazard: Only qualified personnel should perform
installation procedures.
Note: Enterasys Networks recommends installing any
components before powering on your switch.
You can connect to a single, primary source of power, or to two
sources of power for redundancy.
The following redundant power supplies are available to be
purchased from Enterasys Networks:
• C2RPS‐PSM, a 150 watt DC power supply capable of providing
power to a fully‐loaded non‐PoE switch.
• C2RPS‐POE (B2H124‐48P, B3G124‐24P, and B3G124‐48P only),
500 watt DC power supply for PoE switches.
To power‐up your B‐Series switch:
1. If you are connecting a redundant power supply, attach the
C2RPS‐PSM cable (for not 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 B‐Series switch's AC power
receptacle.
3. Plug the redundant power supply (if applicable) and the
B‐Series switch AC power cord 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 the RPS power LED turns
green, and CPU (system) LED turns amber until the B‐Series
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
Enterasys SecureStack B‐Series Hardware Installation Guide
associated with your B‐Series switch for troubleshooting
information.
Completing Switch Setup and Downloading the Latest
Firmware
Once you have connected power to the B‐Series switch and
verified LED activity, you can complete the setup process as
follows. Refer to the Enterasys SecureStack B‐Series Hardware
Installation Guide associated with your B‐Series switch for more
information.
1. Determine the latest B‐Series 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
B‐Series switch with the latest firmware. Table 2 lists additional
configuration commands for your B‐Series switch. For the
complete list of CLI commands, see the Enterasys SecureStack C3
