C1048P Standby
A C1048P stack supports a standby or backup unit that assumes the master
unit role if the master unit in the stack fails. The parent C9010 maintains a
synchronized copy of the running configuration for the stack. As soon as a
stack-master failure is detected, the C9010 initializes the standby unit and
enables all other stack units with the current configuration.
Although the standby unit is automatically selected in the stack, you can use
the command-line interface on the C9010 or C1048P console to manually
configure a different stack member as standby. For more information, refer to
the C9000 Series Configuration Guide or C9000 Series CLI Reference Guide.
Powering up the C1048P
CAUTION: Read the safety information in the Safety and Regulatory
Information manual as well as the safety information for C9000 Series
switches that connect to the C1048P.
The C1048P has one internal power supply. The AC and DC power
connectors are located on the back panel (see Back Panel).
To power up a C1048P, connect it to an AC power source:
1. Using an IEC-320-C15 power cable with safety ground, connect the
power cable to the AC main receptacle located on the back panel.
2. Connect the power cable to a grounded AC outlet.
To connect to a redundant, external DC power supply, use the Dell
Networking MPS1000. Connect the DC power cable from the power supply
to the DC receptacle on the back panel.
After you connect the C1048P to a power source, the C1048P performs a
power-on self-test (POST) and boots up. After a successful boot-up, the
temperature, power, system status, and fan LEDs display solid green. The fans
adjust to an operational speed based on the current traffic load. The SFP+ link
and activity LEDs for the uplink to the parent C9010 display solid green.
