After installing the chassis to a rack and attaching necessary cables, you are now ready to install power and ground cables and apply power to the . The is capable of dual redundant AC or DC power.
The standard platform is shipped with one power supply. A second power supply may be added for redundancy at any time. Please contact your sales representative for more information.
|Before connecting to power, you must connect the chassis ground lug to the chassis.|
All power ratings in the table reflect fans running at high speed.
The following procedure explains how to ground the platform to local earth using a 7/16 inch wrench:
Attach the two hole chassis ground lug PN 300-30016 to the SBC 5100 using two flat washers PN 510-00057, two split lock washers PN 510-00056, and two hex nuts PN 511-00046 as shown in the following figure.
Connect the chassis to local earth ground such that any possible charge is carried off to the earth thus eliminating the risk of shock.
Sonus recommends to route the power cables so that the top power supply cables connect from above and the bottom power supply cables connect from below. This prevents one power supply cable from getting in the way of the other one in case it needs to be removed individually.
The following procedure explains how to connect to the AC power and powering on the switch:
For each AC power supply, insert the supplied AC power cord's female connector to the power supply AC receptacle at the rear of the chassis (shown in the following figure).
In a dual-redundant power supply configuration, the power supplies are hot-swappable meaning that it may be replaced without removing the power supply of platform (provided that the redundant power supply is operational).
|Before replacing a power supply in a redundant power supply configuration, verify the status of the redundant power supply. The “POK” LED status must be “solid green”. Removing the power supply when the redundant supply does not show a solid green status, may cause the system to power down. Contact Sonus customer support if required.|
The following table describes the status of AC power supply.
The following procedure explains how to disconnect from your local AC power source:
The following procedure explains connecting an power supply to the DC Power and power on the switch. If two power supplies are installed, both need to be connected to power before powering up the switch.
Identify the correct size fuse(s) for your configuration and wire gauge before applying DC power to a switch. Also, ensure to switch off the power supply before installing the cables.
Connect ground cable (green) to the screw located above the DC power terminal posts as shown in the below figure:
If applicable, attach the other end of the supplied DC power cables to DC power source.
Do not apply DC power to the DC Power supply prior to hot-inserting the supply into the chassis.
In a dual-redundant power supply configuration, the power supplies are hot-swappable meaning that it may be replaced without powering down the platform (provided that the redundant Power Supply is operational).
|Before replacing a power Supply in a redundant power supply configuration, verify the status of the redundant power supply. The “POK” LED status must be “solid green”. Removing the power supply when the redundant supply does not show a solid green status, may cause the system to power down. Contact Sonus Customer Support if required.|
The following table describes the status of DC power supply.
The following procedure explains how to disconnect DC power from chassis :
Do not remove the DC Power supply without first turning off the power to the power supply being removed from the chassis.
Remove DC power from the power supply and remove the power cables from power supply before attempting this procedure.
To remove the AC or DC power supply from the chassis, perform the following steps:
Refer to the following figures for integrated lever locations:
