PCMCIA NVS Card Caution
Before you insert or remove PCMCIA NVS (flash) cards from a running
CAUTION:
router, we strongly recommend that you halt the SRP module or shut down the
router. Failure to do this can result in file corruption in one or both cards.
The 4XOC3 APS MULTIMODE and 4XOC3 APS SINGLE MODE I/O modules are
incompatible with the following versions of the OCx/STMx ATM and OCx/STMx
POS line modules:
OCx/STMx ATM line modules with assembly numbers 350-00039-xx,
350-80039-xx, and 350-90039-xx
OCx/STMx POS line modules with assembly number 350-10039-xx
When you configure 1:5 line module redundancy by using either the 4XOC3
APS MULTIMODE or 4XOC3 APS SINGLE MODE I/O module, the spare R-Mid
OCX I/O module you install must have assembly number 350-00094-01 Rev.
A01 or later. Spare R-Mid OCX I/O modules with an earlier assembly number
are not supported for 1:5 redundancy configurations that use either the 4XOC3
APS MULTIMODE or 4XOC3 APS SINGLE MODE I/O module.
There is a very small chance that some line modules can have an improperly
modified keying block that prevents the module from proper seating in the top
slot of an older ERX7xx chassis or a preproduction ERX310 chassis. For
example, this problem has been observed for an OCx/STMx module in slot 2 of
an early-test ERX310 chassis.
Work-around: Remove the keying block to insert the module into the top slot,
or insert the module into a different slot.
By design, on the cOC12/STM4 module you cannot delete a serial interface
while data for the interface is still enqueued. The enqueued data can drain only
when the interface is operationally up. Therefore you must ensure that the
interface is operationally up before you delete it. For example, if you have
issued the shutdown command for the interface before you try to delete the
interface, issue the no shutdown command, then delete the interface.
When you upgrade from certain releases to JUNOSe Release 9.2.0p1-0 or
higher-numbered releases, descriptions configured for IP interfaces or IP
subinterfaces are not retained across the upgrade when the descriptions are
shorter than 9 characters in length. Additionally, VRF descriptions are not
retained across the upgrade when the combined length of the VRF description
and the VRF name is shorter than 9 characters. This behavior is seen during
upgrades using a reload, stateful SRP switchover, or unified ISSU. Upgrades
from the following releases are affected by this behavior:
7.x.x
8.0.x
Release 10.0.3
21
