Key points to note on these PWR-M120-AC-S Juniper Power Supplies:-
The Juniper Networks M120 Multiservice Edge Routers reaffirm the technology leadership of Juniper Networks, featuring key advancements in redundancy and scale. The M120 supports a non-disruptive migration to Ethernet services in both metro and WAN environments, while maintaining the integrity of revenue-generating legacy services based on ATM and Frame Relay.
They feature two cFPC slots for 10 GB Ethernet or OC 192 uplinks, preserving the availability of all four Flexible PIC Concentrator (FPC) slots for subscriber connectivity. The M120 delivers support for 128 GE subscriber ports, with 10 GB Ethernet or OC 192 uplink capability in an affordable, compact form factor. Ideal for supporting high-bandwidth converged edge routing applications, the M120 is designed to facilitate service aggregation for the multiplay needs of service providers and enterprise users.
They also extend a cost-effective, Ethernet-optimized infrastructure with 10 GB networking capabilities to the network edge. Capable of supporting MPLS services at Layers 2 and 3, including Layer 3 VPNs, they are designed to deliver superior redundancy and facilitate the transport of legacy Frame Relay and ATM traffic over high-bandwidth Ethernet links.
These Juniper power supplies, with part number: PWR-M120-AC-S are the power supply units designed for use with the Juniper M120 routers. They provide AC power to the router, allowing it to operate and provide network connectivity to your devices.
On replacing these power supplies, for optimum router performance, always first verify the condition of the power supplies.
Check the status of the power supplies by issuing the below command.
user@host> show chassis environment pem
The resulting output should be similar to the following:-
| PEM 0 status |
|
| State |
Online |
| Temperature |
OK |
| DC output |
OK |
| PEM 1 status |
|
| State |
Online |
| Temperature |
OK |
| DC output |
OK |
Make sure that the power and grounding cables are arranged so that they do not obstruct access to other router components.
Routinely check the OK and the STATUS OK LEDs on the power supply faceplates and the craft interface. If these output status LEDs are lit, the power supplies are functioning normally.
Check the red and yellow alarm LEDs on the craft interface. Power supply failure or removal triggers an alarm that causes one or both of the LEDs to light. You can display the associated error messages by issuing the following CLI command:-
user@host> show chassis alarms
Periodically inspect the site to ensure that the grounding and power cables connected to the router are securely in place and that there is no moisture accumulating near the router.
