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).  
14  
12/15/05  
 
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.  
15  
12/15/05  
 
Serial Interface  
The 604/608MFX provides an EIA-232 interface accessed via a 9 pin male  
connector (labeled V24 on the unit). This is used to access the Command  
Line Interpreter (CLI). Functions include setting the IP address, and other  
parameters (see Network Management Users guide). The pin-outs are
