● PSU redundancy is inactive.
● Power budget of the system configuration exceeds the PSU output capacity.
● Grid Redundancy Policy is not selected.
The MX7000 PSUs support the Hot Spare feature with three PSU pairs. The feature enables a PSU pair to have one active
PSU and one PSU in sleep mode while the enclosure power consumption is low, and the three PSU pairs meet all the power
requirements for the enclosure. This enables efficient power utilization when the overall enclosure power requirement is low.
The partner PSU wakes the paired PSU from sleep mode by sending a WAKE signal when the enclosure power requirement
increases. The PSU pairs for MX7000 are PSUs: 1 & 4, 2 & 5, and 3 & 6.
5. From the Primary Grid option, select the PSU where you want to enable the Hot Spare, from the drop-down.
6. Click Apply to save the chassis power settings.
Configure chassis management network
You can configure the network settings for the management modules that are inserted into an MX7000 chassis.
● LAN/NIC interface
● IPv4
● IPv6
● DNS Information
● Management VLAN
To configure the chassis network:
1. Click Devices > Chassis > View Details > Settings > Network.
The Network configuration section is expanded.
2. In the General Settings section, you can enable or disable NIC, Register with DNS, and Auto Negotiation. By default,
the Enable NIC check box is selected.
If you enable Register with DNS, then enter the DNS Name of the chassis that you want to register with a DNS
server. You can access OME-Modular using the existing FQDN even after the Register with DNS option is disabled in
the application. This is because the earlier option remains in the Network cache or the DNS Server cache, based on the
configured Time to live (TTL).
NOTE: You can only access the FQDN temporarily.
NOTE: Clear the cache in the DNS after the Register with DNS is disabled, to prevent logging in with the FQDN
address.
NOTE: If the Register with DNS option is enabled, you cannot modify the Enable VLAN option.
3. Enter the DNS Name. The DNS name can have a maximum of 58 characters. The first character must be an alphanumeric
character (a-z, A-Z, 0-9), followed by numeric characters or a hyphen (-).
4. Enable or disable the Use DHCP for DNS Domain Name option and turn the Auto Negotiation on or off.
If the Use DHCP for DNS Domain Name is disabled, then enter the DNS Domain Name.
NOTE:
You can enable Use DHCP for DNS Name only if IPv4 or IPv6 has DHCP configured. OME–Modular obtains its
DNS domain name from either a DHCP or DHCPv6 server when Use DHCP for DNS Name is enabled.
If Auto Negotiation is false or disabled, you can choose network port speed.
NOTE:
Setting Auto Negotiation to false and choosing a network port speed may result in the chassis losing link
to the network switch in Top of Rack, or to the neighbor chassis, if running MCM. It is recommended that the Auto
Negotiation is set to true for most use cases.
