Enterasys B5G124-24P2 Quick Reference

How to Use This Guide
®
Use this guide to quickly set up your Enterasys B5 switch.
Enterasys Networks recommends that you refer to the Enterasys
B5 Gigabit Ethernet Switch Hardware Installation Guide for
specifications and safety warnings.
The latest B5 documentation is located at
www.enterasys.com/support/manuals.
Hardware Components
The following figures show the several types of front panel port
and rear panel connections on your B5 switch.

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.
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.
Stacking Switches
Up to eight B5 switches can be stacked together and connected by
high‐speed stacking cables, which allow the entire stack to operate
with a single IP address.
The B5 supports the following high‐speed stacking cables only,
which you must order separately:
• STK‐CAB‐SHORT
• STK‐CAB‐LONG
• STK‐CAB‐2M
• STK‐CAB‐5M
Note: You can stack a B5 switch only with other B5 switches.
For complete information about stacking, refer to the Enterasys B5
Gigabit Ethernet Switch Hardware Installation Guide.
Connecting Power to the Switch
Electrical Hazard: Only qualified personnel should perform
installation procedures.
You can connect to a single, primary source of power, or to two
sources of power for redundancy. The example used here
describes connecting to two power sources.
The following redundant power supplies are available to be
purchased from Enterasys Networks for connection to a B5
switch:
• STK‐RPS‐150PS, a 102‐156 watt DC power supply capable of
providing power to a fully‐loaded non‐PoE switch.
• STK‐RPS‐500PS, a 500 watt DC power supply recommended
for full PoE capability.
To power‐up your B5 switch:
1. Attach the power cord from your redundant power supply
into the B5 switch's redundant power receptacle.
2. Attach the AC power cord to the B5 switch's AC power
receptacle.
3. Plug the redundant power supply and the B5 switch AC
power cords into dedicated, grounded AC outlets.
4. Once power is connected, verify that the CPU (system) LED
turns amber until the B5 switch finishes its initialization.
If the initialization process is successful, the CPU LED turns green.
If the CPU LED does not turn green, refer to the Enterasys B5
Gigabit Ethernet Switch Hardware Installation Guide for
troubleshooting information.
Completing Switch Setup and Downloading the Latest
Firmware
Once you have connected power to the B5 switch and verified
LED activity, you can complete the setup process as follows. Refer
to the Enterasys B5 Gigabit Ethernet Switch Hardware Installation
Guide for more information.
1. Determine the latest B5 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 commands
listed in Table 1.)
Basic Setup Commands
Table 1 lists CLI commands that are required for setting up the B5
switch with the latest firmware. Table 2 lists additional
configuration commands for your B5 switch. For the complete list
of CLI commands, see the Enterasys B5 CLI Reference.
