Handling the Switch
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
For
complete
information
about
stacking,
refer
to
the
Enterasys
B5
Gigabit
Ethernet
Switch
Hardware
Installation
Guide.
Connecting Power to the Switch
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.
Caution:
The switch can be damaged by electrostatic discharge.
Note:
You can stack a B5 switch only with other B5 switches.
Electrical Hazard:
Only qualified personnel should perform
installation procedures.
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
.)
