Outstanding Issues with the MX240 Router
This topic lists outstanding hardware issues with the MX240 3D Universal Edge router.
For information about software issues, see the Junos OS Release Notes.
•
On the MX240 DChigh capacitypower supplies, theinput mode switch tellsthe system
what capacity feed is connected (60A or 70A). This is used for power inventory
management. When the input mode switch is set to '0' (zero): expect 60A feeds, with
a voltage range of -39V to -72VDC. When the input mode switch is set to '1' (one),
expect either a 70A feed or a 60A feed with minimum voltage of 42V and up. The
default setting of the input mode is 1 (e.g. 60A with voltages above 42VDC, or 70A).
Known bug: In Junos OS Releases 10.0R3, 10.1R2, and 10.2R1, the MX240 DC high
capacity power supply input mode switch status is not properly reflected in the power
inventory management, generating alarms incorrectly. This does not have any effect
on the operation of the supply. [PR532230]
Important notes:
•
All supplies should have the same feed setting.
•
Correct usage of the feed setting is required for all supplies in order to get the desired
power inventory management.
The XFP cages and optics on the MX240 router are industry standard parts that have
limited tactile feedback for insertion of optics and fiber. You need to insert the optics
and fiber firmly until the latch is securely in place. [PR/98055]
•
Do not mix AC and DC power supplies on an MX240 router. Mixing of AC supplies and
DC supplies may damage your chassis. [PR/233340]
