Make sure all the SHDSL ports in the n-wire group use the same SHDSL profile and are connected
to the same remote SHDSL device.
The DSL ports’ transmission rates are lower than the DSL profile’s configured maximum rate.
You configure the maximum rate of an individual DSL port by modifying its profile (see the
corresponding DSL profile setup screen) or assigning the port to a different profile (see the
corresponding port setup screen). However, the actual rate varies depending on factors such as
transmission range and interference. A DSL port’s connection speed is also limited by what the line
card can support. For example, you can set an SHDSL profile with a rate or 5696 kbps and apply it
to SLC1248G ports, but since the SLC1248G only supports at most 4096 kbps, the maximum rate
one of it’s ports can reach is 4096 kbps.
38.5 Redundant Management Switch Cards
I cannot get a redundant (second) management switch card to work as a standby.
1
Make sure that the management switch cards are in slots 1 and 2 of the IES-5000 main chassis or
slots 8 and 9 of the IES-6000 main chassis. The two management switch cards must have the same
types of uplink and subtending connections.
2
Make sure that the management switch cards both have the same firmware version.
38.6 Management Lockout
You could lock yourself (and all others) out from the MSC by:
1
Misconfiguring the text configuration file.
2
Forgetting the password.
3
Misconfiguring the management IP address.
4
Misconfiguring the management VLAN ID.
5
Misconfiguring the management PVC for IMA line cards.
Note: Be careful not to lock yourself and others out of the MSC.
