For 10/100 Base-TX ports, plug a Category 5 (or better) twisted pair
cable into one the RJ45 copper ports (1-6). Connect the other end to
the far end station. Verify that the Port LED’s are ON once the
connection has been completed. For Switch to Switch or Switch to
Repeater connections, a crossover cable may be required if the
connecting unit does not support the HP-MDIX auto cable detect
feature. For 10/100BaseTX operation, the 600 Series Switch will sense
& adapt accordingly.
A maximum number of 50 600 Series switches can be connected in a
single ring.
CONNECTING MULTIPLE RINGS (608MFX Only)
For multiple rings, the connection between two network segments is
made on two separate paths. Two of the 608MFX’s in a ring are
connected together via a connection cable with an ITP cable (maximum
length of 40m), and inform each other of their operating states. One of
the 608MFX units is assigned the redundant function using the DIP
switch setting “Stby on” (Standby Slave). The other 608MFX unit
takes over the function of the Standby Master, with the DIP switch
setting “Stby off” (see Figure 2). Please note that 604MFX units
cannot be used as Ring Couplers.
Because of the 50-unit ring limit, for larger networks, the user must
configure multiple rings. By using the Master/Slave Standby approach
to couple rings together, the user can enlarge the network by chaining
segments.
Port Assignment in the Standby Mode
On the Standby Master and Standby Slave only port #1 (default
standby port) can be used for the coupling to the neighboring ring.
Connect the #1 ports together using a CAT5E crossover cable between
switches. Ports 2-6 can be used just as normal switch ports.
Simultaneous Standby and Redundancy Manager Operation
A standby master or standby slave can adopt the function of a
redundancy manager at the same time.

“Select/Set” Button
The Select/Set” multi-functional button on the front panel of the
604/608MFX performs the following actions:
•Pressing the button briefly (similar to left mouse click)
transitions the display of the two display mode LED’s. The
current display mode is indicated by the status of the display
mode LED’s per the legend definition on the front of the
swtich.
•If the Display Mode is currently selecting port status (all
Display Mode LEDs off) and if the button is pressed for three
seconds, the Display Mode LEDs begin to flash. If you then
continue to press the button for a further two seconds, the
switch is reset. When the 600 series switch is reset, all the
settings return to their defaults (as set in the factory). This
allows you to cancel settings made from the Web based
management tools, Telnet, or the command line configurator
(serial port), or the fault mask.
•If the Display Mode is currently selecting the fault status and
you press the button for two seconds, the display LED’s start
to flash. If you then continue pressing the button for another
two seconds, the current status of the ports and the supply
voltage are entered in the fault mask. Any change in their
status after the fault mask update will create a fault.
Note: Do not press the “Select/Set” button while the unit is powering up. In
the event that the “Select/Set” button was pressed while the switch is
starting up (approximately a 20-second window), all display mode LEDs
will flash simultaneously. This mode is exited by pressing the button again
after the unit has completely powered up (a 20-second delay).

12/15/05
15
Aging Time
The 604/608MFX monitors the age of the addresses it has learnt, and
addresses that exceed a certain age (aging time, default setting = 40 sec), are
deleted again by the switch. If a packet with a source address matching the
address entry is received before the aging time elapses, the address entry is
retained, and the age is reset. If a packet is received and there is no address
entry for the source address, it is learnt. If a packet is received and there is
no address entry for the destination address, it is sent to all ports.
IEEE 802.1Q, VLAN
The 600 Series switches do not support VLAN tags according to IEEE
802.1Q. Users must configure their networks so that no VLAN packets are
sent.
IEEE 802.1P, QOS
The 600 Series does support QOS. Users should configure their networks
such that no packets with a priority tag higher than 3 are transmitted since
these packets can influence redundancy functions (for example, longer
switchover times if a fault develops, or false fault detection).
Two-Pin Dip Switch Setting
With the two-pin DIP switch on the upper casing of the 604/608MFX, you
can do the following:
•With the Stby button, you can activate the standby function of the
device (608 only). This switch is not connected in the 604MFX.
•With the RM switch, you can activate the redundancy manager
function of the device.
Note: The switch must be restarted after changing the DIP switch
Settings. The switch settings are only adopted when the device powers
Up.

12/15/05
