Power supply configurations

The Switch 5406zl and 8206zl provide slots for two internal supplies and require at least one internal power
supply . An additional internal power supply may be added for 1+1 redundancy system power or to provide
additional PoE power .
The Switch 5412zl and 8212zl provide slots for four internal supplies and require at least two internal power
supplies . Two additional internal power supplies may be added for 1+1 system power redundancy or to
provide additional PoE power .
1+1 power supply redundancy implies providing twice the minimum number of supplies required to power the
system .
Table 3 shows the HP ProCurve Switch 5400zl and 8200zl series minimum and maximum internal power
supply configurations, as well as internal combined power with external power shelf configurations .

When deciding on which and how many power supplies to configure for a 5400zl/8200zl series switch, the
following criteria can be used to guide the decision:
• How much power will be required for each port, full PoE+ (30 watts), full PoE (15.4 watts), or phone (8 watts)
power?
• How many network devices will require power (how many PoE/PoE+ ports are needed)?
• Is redundant power required (for internal power and/or PoE power)?
NOTE: The power supplies provide a "pool" of power for all line interface modules to draw from; that is, PoE
power is not limited on a per line interface module basis .
