OLD-3 APC (unidentified) 192.168.0.240 · dead, no HTTP and no SNMP response on 2026-09-29, replace with SRT-3
PDU rails cross racks: Rack 1 gear sits on rails A and C, Rack 3 gear on C and D. A rack's measured figure below is therefore the output of the UPS standing in that rack, not the draw of the equipment pictured in it. Treat it as UPS load, not rack load.
The three SRT2200 units are racked and on the network but carry no load yet: all three report 0 percent. Rack 3 has no Symmetra and its old 0.240 UPS answers nothing on HTTP or SNMP, so rack 3 is the one rack with no measured protection today. Its estimate of about 2,000W exceeds the 1,980W an SRT2200 can carry, which is why its feed is a decision and not a plan.
Proposed feed plan

Status
Detail
Rack 1
SRT-1 (3.250) takes PSU A of all five Rack 1 cluster nodes, the firewall and both core switches
SRT-2 (3.251) moves into Rack 1 and takes PSU B of the same set
ok
This is the whole point of the exercise. Rack 1 holds five of the six cluster nodes (JMFPMX02, 03, 04, 05, 06) and they draw 922W measured, not the 4,350W their nameplate claims. One SRT2200 carries all five at 47 percent, so two of them split across PSUs sit at about 24 percent each and still hold the whole rack at 47 percent if either dies. SYM-1 is then left carrying only the Syn NAS and the ISP handoff, and its habit of dropping to bypass on every transfer stops being able to take the cluster down.
Rack 2
SYM-2 (0.239) keeps PDU rail C
SRT-3 (3.252) as the second feed for the two R520s and the R710
ok
Rack 2 draws 1,218W measured against 4,200W on SYM-2. SYM-2 is the healthier of the two Symmetras, though its last self test returned invalid rather than passed on 09-24.
Rack 3
unchanged until it can be measured
decision
Rack 3 still cannot be measured: its two PDU rails have no management IP, and its old UPS at 0.240 is dead. Two of its R740s do answer over iDRAC and draw only 90W and 115W, which suggests the rack is far lighter than its 6,310W nameplate implies. Address the PDUs and this stops being a guess.

IDENTITY UNKNOWN. The drawing gave it 192.168.0.1, but Greg confirms 0.1, 2.1 and 3.1 are all gateway IPs on the 192.168.0.201 backbone switch, so that address is not this device. Whatever occupies this U is unidentified.
