circuits on the Backplane, as well as removing any heat generated by the power modules.
Warning! Do not open or remove the Front Door when the unit is powered. The door of each VX
Router contains air baffles that are integral to the chassis’ cooling system. The Backplane
Integrated Circuits may overheat when operating with the front door open or removed.
Note: When mounting the chassis in a rack, insure that the fans
’ air flow is not restricted.
5. The temperature in the chassis is monitored in several locations. The power supplies have an
internal temperature sensor that is monitored constantly for any condit ions that may
indicate a problem. Other temperature sensors are mounted in the fan trays, on the
Controller card(s), on the I/O cards, and on the Backplane.
Note: If any of these sensors detect an over temperature condition, power will be removed from
all sensitive components and the system will shut down.
6. As a further safeguard, all fan speeds are monitored and any fan speed that does not meet
specification will cause the unit to set an alarm condition.
Note: All failure conditions send out notifications prior to shut down. For a detailed list of the
alarm descriptions, see page 17.
7. When the VX Router has been inspected and found to be in good condition, the installation
process can begin.

How to Replace Modules
How to Install or Replace Input/Output Cards
Note: No shutdown is required prior to installing/replacing Input/Output Cards.
Step 1: Turn the two thumbscrews counterclockwise until they disengage from the chassis. Pull the card out
using both handles.
Warning! Do not pull on the thumbscrews when removing the module – damage may occur!
OR: If a blank panel is present, remove the blank panel from the desired location using the thumbscrews.
Step 2: Place the new module upright so that the POWER LED is on the top. Grasp the module by
the handles or by the outer edge of the aluminum housing. The card should slide freely until it
reaches the backplane connector. At this point, use just enough force to firmly engage the card with
the mating connector.
Warning! If the module does not slide into the connector, do not force it! Damage may occur.
Remove the card and start over.
Step 3: Once the module is completely seated, hand-tighten the thumbscrews.
Warning! Do not tighten the thumbscrews with a screwdriver.
