Replace Power Supply - Cisco 8011-2X2XP4L Hardware Installation Manual

Replace Power Supply

The router provides a choice of two different power supplies as AC and DC. The router also supports a
combination of AC (PWR-400-AC) and DC (PWR-400-DC) PSUs together:
• DC power (PWR-400-DC)—The DC power supply uses two-position terminal block-style connector
with positive latching or securing, and labeled connections for +24/48V, GRD, -24/48V. The terminal
block connector is of suitable size to carry the appropriate AWG wire size to handle the input current of
the power supply. No ON/OFF switch is provided.
• AC power (PWR-400-AC)—The AC power supply has an IEC 320-type power receptacle and a 15 Amp
service connector. You can use standard right angle power cords with the AC power supply. The power
supply includes a power cord retainer. No ON/OFF switch is provided.
You can install dual power supplies for redundancy.
Note Products that have an AC power connection are required to have an external SPD provided as part of the
building installation to comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility
and safety.
Caution
Don't use interface module and power supply ejector handles to lift the chassis; using the handles to lift the
chassis can deform or damage the handles.
